We had a great stay with Korina, Jimi and her boys. Although we did not spend much time at their house, they were easy to communicate with, very accommodating and easy to stay with, being very flexible and quiet. We stayed to both visit London and go to Wimbledon for tennis which worked out perfectly. Being close to Clapham Junction, we were able to ride the 39 bus at 4:30am, get in the Wimbledon queue and have a great two days at Wimbledon. I highly recommend staying with Korina for Wimbledon (particularly since you can avoid the tube which gets crazy when leaving Wimbledon). Being close to Clapham also made it easy to visit central London and as many have said, her neighborhood is a "real" London experience and has everything you need during your stay.
