Lovely, pretty flat that felt much more spacious than the photos. Gorgeous light and breezes come through the large windows and doors. The kitchen has everything you could need (pots, utensils, cooking staples) and everything seemed fairly new. Wifi worked great, bed was very comfortable, lots of towels provided. Furniture is an odd, mixed bag (given how pretty the flat itself is) but that's ok!
Location was great - lots of pretty, quiet streets to walk around and easy enough access to buses and Tube links.
Given the extreme heat that London has been having, a fan would have been really useful.
