The communication with the host wasn't good. I asked 5 times to fix the online form for paying the tourist tax but didn't get any satisfying answer. Luckily, we managed to figure out the issue on our own and get the digital key on the night before our check-in date.
We couldn't find the apartment first, because the host said it was on floor 3, while in fact, it's on floor 1 (just press 1 in the elevator).
The digital key stopped working 1 hour before the announced time of the check-out (11 am).
The property wasn't clean, covered with dust and hair. There was no soap in the bathroom. We had a tiny 3-times use shampoo and shower gel for a group of 7 people. We were given just 1 extra bag for trash and not enough toilet paper.
Pay attention that some rooms are too small and practically with no windows (small windows facing the building wall). The ceiling on the 1st level of the apartment is super low (the men couldn't stand straight).
Nevertheless, the location is excellent. And having the digital key is convenient for a big group of people.
