I was in London with a friend for the week-end.
Our stay at Clare's was perfect ! She was really kind to us and not intrusive, she gave us all the information we needed, we were like at home !
The room, as well as the house, is spacious, modern, and very well-equiped. And the bed... you should definitely book at Clare's just for the bed ! ;-)
If you're afraid the location is far from the center, let me reassure you : the house is in a very quiet area, it is only 6mn walk from the bus ( the 57 is 24/7) and then 5 from the Tube. You will be in the center of London in max 30 mn. The tube is also a night line on Friday and Saturday, so that's a very good point :)
Hope you will enjoy your stay at Clare's ! Thanks again for this week-end !
