Katherine's flat is amazing!! Very well connected, lots of pubs, restaurants, and supermarkets around. We stayed 4 nights at her place; we hired a bike everyday; it took us 20 minutes to get to Hyde Park, and 30 minutes to reach the Big Ben. Tube is nearby too. But biking is a really nice experience in summer. The flat has everything you need. It's cozy and elegant at the same time. I would definitely come back again!!
