I had a nice stay at Rosemary's. She's friendly and is always around if you need help with anything. The room is cozy and sunny, and the place is very clean. The flat itself is on a quiet block but it's about a 10-15 mins walk to the busy shopping area in Wimbledon where you can find all kinds of restaurants and grocery stores. She allowed me to cook as I was staying over the holidays and a lot of places were closed, which I'm very thankful for.
Rosemary's place can definitely benefit from better internet though. Right now it's a bit on the slower side.
