Highly recommendable!
Flawless check-in, when necessary with keybox. There was one couch convertible into a double bed and two really cool beds right under the roof - very cozy. Kids (and also adults!) love that. Maybe not for claustrophobics though.
Getting up to the apartment was via a very narrowly winding staircase outside so elderly people would need some help I guess. I loved how we had a separate entrance though - lots of privacy for the hosts and for us.
The living area was brand new, sparkling clean and beautifully furnished, very modern. We cooked several meals and found everything we needed, even a dishwasher.
Located in a beautiful, quiet residential area, 25min by bus from the central station. We (three female students) felt very safe there
