Unfortunately, the description of this accommodation is not accurate. It implies that there are two separate bedrooms "...one double bedroom and a separate bathroom, and one 'single bed (futon on floor) with a gorgeous' ensuite..." And that 5 people or more could stay there. In fact, there is only one double bed in one bedroom that is suitable for anyone to sleep in. The rest of the "bed arrangement" offered is completely inadequate. What you find in the living room - and not in a separate room as implied in the advert- is a sofa (which by the way was very dirty and not suitable to sleep on) plus a small futon on the floor. I was in London with a colleague for one night attending an important business event. Before visiting, I exchanged messages with the hosts explaining that I was there with a colleague and asked to confirm that the flat had two separate bedrooms. I was truly embarrassed with my colleague when noticing that the place only had one bed and one bedroom.
This was a real shame and truly disappointing because is fair also to say that the accommodation is in a very nice, quiet location, close to an underground station, tastefully decorated and the host was quick to respond and friendly. I understand why people have given this space good reviews. If you are there either on your own or with your partner or with someone who doesn't mind sleeping on the floor then great, you'll be OK. Otherwise and if needing two beds for two or more people, then try elsewhere.
