We stayed at the appartment for a weekend. The location is perfect, every big sight is reachable by foot and there are a lot of cute restaurants, cafes and a supermarket nearby.
The apartment is very clean and has everything you might need, even a hair dryer and microwave.
Also the communication worked very good and he answered right away, when had questions.
Overall it is a perfect apartment for a short or also longer trip. We had a great time!
