We had a wonderful stay at Catherin's place. The flat is in a great location -easy access from Heathrow, right on the convenient Picadilly line. It's close to major tourist attractions, walking distance to Hyde Park and lots of restaurants. There are even two supermarkets within a minute's walk!
Catherin had great communication, responding quickly to all my questions ahead of our stay. She is a gracious host and I couldn't recommend her place more highly. We'll definitely stay there again on our next trip to London!
