Lydia's flat is superlatively located to travel around London. My partner and I stayed for 11 days on a research trip and we had a wonderful time, both working in and exploring the city. The flat is well-situated in Brixton and is close to lots of eateries and shops (Brixton Village, Brixton Market, and Pop Brixton, for starters). It's also an easy walk to the tube as well as the Thameslink. Both Lydia and Alex were very helpful as we made and adjusted our local plans, and even had excellent suggestions to deal with a temperamental British summer. All in all, a fantastic experience.
