Our stay was okay-ish. The appartement is on the 4th floor without an elevator, which isn't mentioned in the description (as a person with lung problems, this had been misleading) . Cleaning could be improved (hair on bathroom and toilet floors), as well as the carpet in the shower (kind of carpet that sucks in the water, but never dries out). The towels had a mildew smell.
The room was big and clean, bed was decent. WiFi router was on our bedside table, which we weren't big fan of.
The appartement was well located and we did not use the kitchen.
I guess it's a good place for a short stay. Communication with Niko has been narrowed down to essential things (check-in).
