The location is very pleasant and close to the historic center and public transport. The room for two people was spacious as well as the bathroom. The bathroom was really nice!
The owner likes art, especially modern design and is a fan of architectural literature.
I would suggest everyone to book the rooms for two people, since the room for one is tiny even for someone wearing "s" size. In the bigger room I could hear the neighbours nextdoor (at least 3 or 4 drunk French speakers) which arrived late in the night and made noise for a couple of hours.
