Tina's place has a great location for exploring the city (a bus took us about 20min to BigBen) and the place has just been renovated with good taste so it was new and beautifull. Tina communicated well, was flexible about checkin/-out times and recommended a excellent italian restaurant for us.
As the house is shared, we did we did have to listen to the afterparty of the other guest(?) for a few hours but otherwise we had no problems.
