For a family visit to London, both the location (five minute walk to the nearest tube) and sleeping arrangements (two bedrooms, each with a double bed) were excellent. However, the apartment itself is very basic: don't expect anything in it - no tea, coffee, or even salt or sugar. No soap bar or shampoo, things that almost all airbnb hosts give. The wifi was very bad - couldn't keep a connection for more then a few minutes. And worse of all, we all had nightly meetings with cockroaches running around the apartment.
All in all: a very basic and not so well kept flat, with little regard to guests basic needs that could have made the stay much more pleasant - but quite spacious and at a good location.
