A very nice find! Stayed at Dani's place for 2 weeks while studying and seeing the sights and it's in an amazing location, about 20 minutes travel away from anywhere in London. The host was away most of the trip but there was a lovely lady who was there to sort things out for us. The only real issue was the laundrette facilities which are fairly small and almost always in use, I did have some trouble finding a free machine.
If you need a place to stay in London this is a very good choice!
