Some friends and I (in total 6 persons) had a really nice stay in this apartment - enough space, a cool „sleep-over-bedroom“ and a good location
As we read the comments before, we knew that other guests experienced some issues (not enough towels, no warm water, dirty parts, not enough things in the kitchen,…) so we checked those directly at the beginning. Everything was ok, except for the supply of warm water. After the boiler was re-started by the guy letting us in, the warm water worked, too.
Having only 1 key can be tricky, especially because the flat’s front door can only be closed if it is locked
All in all, recommendable :)
