I stayed 4 nights with my 5 years old daughter. The flat was really well-described, really close to the metro (Bakerloo Line) and from the Westminster Bridge and the London Eye. A lot of buses are also available. What we appreciated most was the quietness in spite of being into the city, and the possibility to cook. It's possible to sleep in the bed and in the couch, bith very comfortables. No TV but a good wifi connexion. Towels and sheet provided.
Catalina wasn't there but she let the keys in a easy place to find and responded to all messages. We had a really nice stay
