The apartment is comfortable and very centrally located, in the heart of the Gothic District and 3-5 minutes walk from the metro. Check in was easy.
For check out: the door at the bottom of the stairwell has a deadbolt. Do not leave the keys in the room and then get stuck at the bottom of the stairwell.
Also, the street that it is on is somewhat unfavorable. I was here with my parents, and given the street we were on I would probably have picked somewhere quieter & cleaner (location, not apartment).
