We really enjoyed our stay at Mercedes and James' flat. Very spacious and comfortable and Mercedes and James assured us we were welcome to use everything and were super friendly and welcoming when we arrived. The flat is down the street from a few small markets, coffee shops, restaurants, and the nearest tube station. Unfortunately while we were here the tube line was closed for maintenance but we were easily able to get to nearby bus stops and find buses to take us straight to more central locations. About a 15 minute walk from Abbey Road studios!
