Owner is a very very pleasant man. Checkin is easy, even in the after-hours when there is no one there.
Building has a lot of the old Maastricht charm, with a narrow, steep, spiraling staircase. Rooms are tastefully decorated. Mine, had some vintage radios and metal lockers, and an original painting for sale. Location is very central. The shower always had warm water. The heaters work very well to keep the room warm.
The building being old, you do hear creaks and cracks as the neighbors upstairs walk about, so be warned if you are a light sleeper.
Also, if your room faces the courtyard, it is quieter than if you face the street, unless someone sits in the courtyard and talks, in which case the sound echos into the room when the windows are open.
There is no A/C or fan, which is seldom needed in Maastricht, but for you to know if you like it very cool when you sleep.
