We've been surprised by the size of the flat that didn't match with the pictures we've seen (there was a patio in the announce that was not there) and we've shared the bathroom and toilets with another flat. That wasn't mentioned either. Also, we were told that a welcome bottle of wine would be offered but we kept looking and there was none !
Otherwise, the location was very good, very close to the subway and the town center. The flat was very clean and we've spent a good time in London !
