I had a very pleasant stay at Mattias with my family of 3. They house is exactly what you see on the pictures: spacious and comfy. The flat is super close to the station, and if you don't mind changing lines, going central is easy. We had a few problems with the neighbors refurbishing their house, it was really loud at times, but would never go on for too long. Obviously there is not much that can be done about that though.Anyway, I highly recommend this flat if you want a good time in London.
