Great stay, I've enjoyed it a lot.
Location is great, very lively but not so touristic area. Very close to the train station.
The attic is very cozy, not big, but has everything. Good shower, AC, bed etc. Washing machine is an additional bonus. Has a very local feel. Very quiet at night.
Yes, the stair is steep so keep this in mind if you are bringing a big luggage. But it's a historic building so that's totally understandable.
