We enjoyed our stay at Madeleine's! The Station is pretty close and it was easy to get to Central London within ~half an hour. Buckingham Palace and Hyde Park were super close, which is a Plus.
Tesco Express is only a few steps away from where you'll live and has everything you need!
The interior of the flat was very modern and simple, you won't miss anything. Only thing was, that the floor is pretty creaky, so best don't walk around too much when everyone else is already asleep. Walls are pretty thin, but we didn't really find that problematic:)
Madeleine was a very nice host and we would like to thank her by heart for the great weekend we had in her accommodation! We had a great time!
