I've been looking for a hotel for me and my 2 grandkids, and figured I'd just book again at the Premier Inn County Hall. But I was a little worried about size, as there will be 3 of us and we will be there for 9 nights. I know they have family rooms, but they don't really look that big. Plus my grandson really wanted to be near Buckingham Palace. :-)
So I was checking around and remembered some people here talking about The Resident hotels and how nice they were. There are four of them in London, so I went to the site and found a perfect deluxe room for 3-4 people at the Victoria location, which includes one king, one twin and a mini-kitchen complete with fridge, microwave, sink with BRITA filter tap, kettle, crockery, cutlery, glassware, Nespresso coffee machine, coffee capsules and Taylors of Harrogate teas. Lots of space, too.
Originally the lowest prices was around £2250 for 9 nights, but if you are a member, you get 15% off. Plus they have an August sale going on right now (until midnight on August 13), which reduced the price even more for members (and a lesser amount for non-members). So I joined up (it's free) and by the time they took the sale price off and the member discount, it was down to around £1870. Needless to say, I was thrilled and the location is great; right off Birdcage Walk near Buckingham Palace.
So if you are looking for something for the future, you might check here. My stay isn't until late March and early April of next year, so there is evidently no need to arrive by a certain date. You just have to book by the deadline. https://www.residenthotels.com/offers/limited-time-sale/
UPDATE: See Frank's post below about the non-refundable rates. Although I do believe that if you are a member, you can still get a discount for flexible rates.
