Daria is a very discrete host, available by phone and though messages.
The room is very nice, large and quite, with a big bed and two windows.
The bathroom is private, the sink is very small, the shower is ... creative!
The position of the house is perfect, 5 minutes from underground station, two stops from London Bridge. Also I used the bus since there is a bus stop near the house. The area is quite and safe.
I strongly suggest this location if you want to stay near the center.
