Nothing but great things to say. We had a full house of friends and family, and this was perfect for the six of us. The house is filled with windows and mirrors, keeping things light, the kitchen has everything you need, and we all enjoyed the fun decor and beautiful yard (we were spoiled with some summer-like weather in March). Absolutely recommend this flat. While it's always nice to be walking distance from a tube station (which this is not), the bus lines take you anywhere you want to go quickly and easily (including to Vauxhall or Gloucester Rd tube stations), and there are many trains from Clapham. In Battersea, within a 5-10 min walk, you have the park as well as quite a few restaurants/bakeries/bars/pubs.
Joe worked with me to make the dates work, and check in and check out were very easy. Again, great stay.
