London accomodations advice 12 days

Try Aster House. It's in the South Kensington area.

http://www.asterhouse.com/

Each neighborhood is fine.

If had to rank neighborhoods for first time visitors would go with S Ken, Fitzrovia then Paddington.

If you do go with the Cranely Mews or Cranely Road in S Kensington don’t miss having a spot of tea and cake at the V & A. Great gift shop as well.

Have chicken at Nandos.
Easy walk to see the Albert Memorial in Hyde Park.
TESCO Express for groceries.

Book it and be done with it.

Great city. Have a wonderful trip with your daughter.

We rented this flat in South Kensington for 10 days last September and shared with another couple. We found it to be a perfect location between two tube stops, plenty of restaurants, several museums, Kensington Gardens and Hyde Park. There are several options for picking up groceries and wine if you like and the neighborhood was very safe when we went out to dinner and returned between 10-11. I would not wait much longer to get the dates you want.

Thanks for all the great suggestions, I think we're on the right track.
Looks like The Asterhouse is more of a Bed and Breakfast without any kitchen options, but I'm still checking it out. No pics either.
Thank you stmurray2... looks like something we would be interested in but unfortunately our dates are not available.
Will continue to research but need to make decisions soon.

I’d also check availability at the Vancouver Studio Apartments in the Bayswater neighborhood. Used to be my go to place to stay until a friend moved to London and that is where I stay now.

Vancouver Studio Apartments are clean, safe, and still a good price. No elevator if that would be an issue and when I stayed there it was a room in the original building. One bed apartments operated by them now are close by.

I liked the diverse Bayswater neighborhood. Lots of good cafes. The two tube stations, 20 minute stroll to Portobello Road Market, 10 minute walk to Kensington Garden and Kensington Palace, 20-25 minute walk from Paddington Station.

Can walk through Kensington Gardens past the Palace over to the V & A in 30 minutes.

Take a look and see if it’s of any interest.

We have rented from www.londonconnection.com three times and loved each property. They are all over London. Great service, very personalized .

I concur with Claudia on her recommendations of location preferences for first time visitors. BTW, Claudia and Emma were instrumental in making my London trip so enjoyable at Christmas this past year, their recommendations are spot on.

I agree that with 12 days a flat can be more economical, but if you do decide to stay in a hotel or B&B, I can provide some additional color on Aster House. This is where I like to stay when I am in London and I have been to London over dozen times over the years and stayed in different hotels and different locations and I keep coming back to Aster House. It is run by a lovely woman Leoni and her husband. She is such a gracious hostess and breakfast comes with the rate (eggs, toast, pastries, fruit, meat, etc.). It can be expensive, but frankly it is not outlandish for the area. They have a lovely garden and if you are staying for 12 days, you might want to opt for one of the larger rooms. We stayed for 9 nights in December and we didn’t feel cramped, but we also didn’t want to cook.

Enjoy London,
Sandy

I stayed near Paddington on my last trip because I was going to be using the station several times for day trips. Otherwise I wouldn't recommend the area -- not because it's unpleasant or unsafe but because it's less convenient for sightseeing than the others you're considering.

This is my first time using the RS Travel forum and it's proving to be the best decision. I'm now focusing on all the great input and tips and hopefully will book in the next couple days after a little more research. Some of the suggestions I've already checked into but either my dates were not available or over my budget.

The other interesting thing I've noticed is that alot of places have no cancellation or restricted cancellation policies. I prefer to book accommodations that have at least 30 day before arrival free cancellation.

We loved spending ten dayws in a lovely apartment in Chelsea, near King’s Road and the Thames. We booked it through London Perfect, great service.

Check Airbnb. I recently booked a place in London with a moderate cancellation policy. That's one reason I chose it. There isn't any availability in September for that one, but I'm sure you can find something.

We are heading to London this summer and was directed to "London Connection" on this forum. The US based company rents out centrally located flats throughout the city. We are staying in a one bedroom a block from Trafalgar Square. The flat has a kitchen and laundry and is minutes from a grocery store. The site has pictures and reviews for all their properties and they will pick you up from the airport.

You could see if the “London Rooms” flat at Captain Bligh House is available for your dates.

It has a kitchenette, living area, and twin-bedded bedroom. I realize the location (south of the river) is not on your preferred list, but it is a convenient one for transport and also for walking. Note that it is on the second floor with no lift.

Thank you for all the advice and suggestions. This is turning out to be more difficult than expected. Discovered It is high season when we go, so plenty of the accommodations I've looked at are not available my specific 12 days, over my budget or very strict/or no cancellation policies.
I decided to also research under hotels that have "apartment / self serviced" styles. The couple that might be of interest so far are Residence Inn by Marriott, Kensington, and Clarendon Pepys Street, and Clarendon Minorities...any thoughts???

We have had good results in London with https://www.wimdu.com

And I really like Southwark.

You can also use booking.com to look for apartments, using the filters to limit the search to your dates and preferred areas.

Here is one example (for a random 12 nights in September), a one-bedroom with sofa bed in the living room, near Tower Bridge. $2200.

I appreciate ALL the feedback. I never considered staying on the south side of the River Thames. I might sound "naive" but what is the transportation like from that area to the other touristy attractions across the river? Buckingham Palace, British Museum, War Museum, Windsor Castle, Tower of London etc ....Tube, buses etc
Also planning a couple day trips possibly Stonehenge, Cambridge, Harry Potter studios..how convenient to pick up locations

Any feedback on these 2 options? The Clarendon Minories and Clarendon Pepys St
