We really enjoyed our stay at this VRBO. The location is amazing: it is close to the Victoria Station (which can get you anywhere) but away from busy streets like Oxford. I would say this is situated between the two neighborhoods (Pimlico and Belgravia) where the locals live. It is a short walk to several grocery stores, including a pretty big one, bakeries, pubs, pretty much everything.
The flat itself was great. It was all on one level, very spacious with comfortable beds and a cozy kitchen. The main room had a great round table next to a window (a great spot for breakfast or an evening chat). There were two bedrooms, both very spacious and comfortable. Also, the futon/couch in the main room transformed into a bed. There were a lot of other amenities we did not try of use (baby crib, baby chair, humidifiers, etc.)
