The location is great. Close to the Baker Street tube station and to some bus stations, and also close to Regent's Park. The owners were friendly and the communication was easy and pleasant. The were some minor issues with some of the sheets and the lamps, but they were handled quickly.
We were four adults. One bedroom is bigger and also has its own bathroom, the other one is smaller. The living room is nice, with both a place to sit and a dining table. The kitchen was also good.
Overall we had a good experience and would recommend this apartment.
