I went to London for a trip with some friends and we really had a good time at Donovan's place. The house is clean, peaceful and a really comfortable place to visit the city. You get to the Tate Modern and to that side of Thames in 5-10 mins on foot...it's very nice to have a walk there in a sunny day! You are also really close to Westminster area. The zone is also pretty safe and there are nice pubs there, if you want to stop for a beer (better an ale!) before getting home... The metro station is 3 mins walk and even if Waterloo is a very big one, the area seems to be safe at each time of the day and night. About the host... Donovan was a nice one!He's gentle, discreet, but helpful...he gave us information about anything we asked for and we also had some interesting talk with him...I would recommend him!
