I stayed for one night with my family.
Pro:
we liked the flat, it’s nice design elements, the well equipped kitchen, comfy beds and its thick windows - it’s not loud at all although it’s in the centre and a crowded street is in front of the apartment.
Cons:
Check in procedure was too complicated and time consuming for a one day family trip. The host called about 10 times and wanted to have lots of stuff and infos (passports of all family members; photos; additional safety deposit)
