Our stay at Ursula's place was absolutely exceptional. The flat is comfortable, spacious and extremely clean, with wonderful touches that make it somewhere you really look forward to coming back to after a day exploring London. Being able to have breakfast outside in the small garden is a rare treat in London.
Clapham itself is a lovely area, with a large park that is ideal for picnics, some of the best restaurants in London (e.g. the Dairy), and great transport links via the Northern line.
But the best part of our stay was undoubtedly Ursula herself. Exceptionally helpful and attentive, she made sure we had everything we needed throughout the trip, and was very accommodating when a few travel mishaps meant we needed to change plans at the last minute. She is a wonderful advertisement for hosts in London, and I could not recommend her flat more highly
