Sarah's flat was absolutely perfect for my solo stay in London. The interior of the apartment is well designed, pristine, and comfortable. I was a little worried about it being a sub-level unit, but was very pleasantly surprised by how much sunlight there was in the unit throughout the day. I was in London during this summer's heatwave, and the apartment was consistently cool and comfortable all day long -- even when it was 104 outside! The location is also wonderful -- the street is cute and quiet, and there are several tube stations nearby that can get you anywhere very quickly and conveniently. Flat had literally everything that I wanted and needed, and Sarah was a friendly and communicative host during my stay. Would definitely return for my next trip to London!
