The hosts are very friendly, responsive and flexible. The place is rather chilly in winter, but the duvets in the bed are big and thick enough to keep you warm at night. The bathroom is clean, and the shower is nice.
The place is located near a metro station, but if you're coming from the train station, there is no direct connection. It's also very noisy and there isn't much gastronomy around it. The good thing is that it's located very near to the old river which is now a park, so it's a nice 30 min walk towards the city.
Note, there is no lock in the room and in the bathroom. For us, it wasn't a big deal, but for someone who feels insecure about this, this might be an issue.
Important for those who have difficulties climbing stairs: the flat is on the second floor and there is no lift.
