Sandra's studio is so lovely that this was my second stay. Both she and Derek are super friendly and very kind but not intrusive and I feel very relaxed there, and the location is perfect, a few minutes easy flat walk to the tube (District line straight in to the city).
The ensuite room is stylish and immaculate with nice extra touches such as a selection of fruit, croissants and fresh milk.
I also like to have the windows open at night and haven't been bothered at all by noise. If any downside at all (and I have to search my brain to find one) its that I'm not a fan of the rain shower type fitting in the bathroom, but that's only a personal preference and hasn't stopped me from wanting to come back - I've booked another stay there!
