I ran into an unprecedented and unforeseen situation, perhaps due to heat, unusual for London finding an odd smell and a few jammed windows in the living room.
The host was hospitable and helpful after the first few hours, would have appreciated if it was immediate.
I would advise other guests to look up the exact location and neighborhood for this place, if it is to your liking and expect a little difference from the photographs which are similar but more beautifully rendered.
