Katia's flat is perfectly situated for exploring Wimbledon Village and the surrounding areas. Though the flat itself is very quiet, it's within a block to buses and a mini-Tesco (for basic groceries), and a short walk down the hill to trains/Underground.
The flat is more spacious than it looks in the photos and we found it to be very comfortable. It was 85-93* out during our stay and the flat stayed fairly cool. Having said that, we appreciated having a much-needed/necessary fan available to help circulate the air. Laundry access was also great and meant we didn't feel we needed to pack as much for our trip.
I made a few suggestions to the host to help freshen things up a bit. It should be noted that the queen bed is actually two singles side by side, which worked well for my son and I but other guests may not be happy with the small valley and ridges that run vertically between the two halves.
We'd be happy to stay again the next time we are in Wimbledon!
