We really loved our stay here!
The location is very central and we visited almost everything by foot or within 20 minutes by train/bus. The possibility to store luggage in the basement before check-in and after check-out is very unique.
The room is directly under the roof, so you are totally on your own. There is one towel per person provided, but the host also offers the possibility to order more towels/room cleaning etc. per link, which is an outstanding service. In the bathrooms there is shower gel, shampoo, and conditioner available.
We stayed 3 nights and would be very happy to stay here next time again.
