Stayed for 3 nights with wife and 2 kids : 7 and 9yo.
Location is close to city center 10min walk.
Not the most beautiful area but it works.
Flat is decent, clean.
Building is noisy : doors, music, neighbors which is somehow polluting the experience.
Particularly at night.
Mattress extremely soft which is a problem for me, not for everyone.
Flat is cold. Temperature can be slightly increased upon request to owner.
Overall owner very attentive and thank to him for that.
