Great location, easy and short walk from attractions and public transportation. Jan was extremely flexible with check-in and check-out, and communication with him was really easy. The place itself is gorgeous - high floor with a great view of the city, very clean and very pleasant. Also very quiet.
We were four single people, so two of us slept on two (good) beds in the open space of the apartment, which was fine. Two others slept in two separate rooms.
