Inexpensive B&B's in London

Bob,

London may just be the most expensive city in Europe and I rather doubt that you'll be able to find a traditional hotel room in Zone 1 for under $100 a night. You might, however, want to look into hostels. Several of London's hostels offer private bedrooms for under $100 a night. Another alternative is finding a private bedroom in a private residence using AirBNB or other such site.

Try the Arran House Hotel. We stayed there in 2008. they had a very good breakfast and it's in a great location. It's very basic - nothing fancy, but it is on the less expensive side. I found it from Rick's book back then. Not sure if it's in the current edition.

Have a look at TripAdvisor and put in the criteria that you need.
I found many budget hotels around your price and I always look for subway line near by.
In TripAdvisor you can see click on a map for each hotel and see where they are located.
If you find some that interest you - maybe double check with readers on this forum to see if they have any recommendations?
I usually stay at the Jesmond Dene on Argyle St a couple blocks from Kings Cross station.
But their prices may have gone up.... they serve a very large full English Breakfast too.
PS they give you a discount if you pay your bill in cash....

increase your budget or look at university accommodation

Look at the YHA hostels. They are much improved over the "old days" when they were a last resort.
You can get a private room and stay for as little as 49 pounds per night.

The YHA hostels in London function like hotels. They have a front desk for check-in,
you have a key card to get into the building, elevator, and room.
Several have a cafe for breakfast.

One of the best locations is the Oxford Street hostel.
Very good location with tube and bus transportation nearby.

They also have one in Earl's Court, which is on the main tube
line to Heathrow.

The words "inexpensive" and "London" rarely appear in the same sentence.

Book NOW. Both the Premiere Inns at St Pancras and Kings Cross are offering a rate of $113.00. You'll be close to the British Library and the Treasure Room. Tube stop nearly out your door. Clean, basic, comfortable rooms.

Many of the lodgings in London are hotels. But some of the small hotels are family owned
and run, and they feel like a B&B.
There are not a lot of B&B's in London. Those are mostly found out in the countryside
and in towns smaller than London, such as Bath, Salisbury or Statford-Upon-Avon, etc.

Claudia is right. Grab one of the rooms at the Premier Inn.
That's a great price. Nice clean hotels with a good breakfast.

Falcon Hotel, 11 Norfolk Sq has single ensuite rooms for £69.00, it's a five minute walk to Paddington tube station.

I just booked a week at the Jesmond Dene Hotel. Good reviews, a bit less than $100/day, full breakfast, and right next to St Pancras. It sounds perfect for me. Thanks everyone.
