Amazing place!
Location is really good because it's two metro stops away from the heart of the city center, but, unlike the central station area, it feels friendly and safe to walk there at night.
Also, even if you like to party late, and return home without a cab when there are no subways, the central station is a walking distance from the apartment (15 minutes).
Furniture and bed were comfortable and served all our needs. The smart TV and BT speakers were awesome.
For some strange reason the TV internet didn't always work, even though the flat's WIFI was working, but to be fair we did not bother contacting the host about it while we were still there.
Shower was very nice and the place was absolutely beautiful. Also, having the toilet separate from the shower is a really nice bonus!
Philipp, the host, was very helpful and highly available. He always gave us tips and helped us with whatever we asked.
The only real downsides for this apartment for me were:
1. Four stories with no elevators. It can get really tiresome to climb these stairs, especially if you return to the apartment often. The stairs also creeked, which made me feel bad for the neighbors when I left or arrived late at night.
2. There was no washing machine, but there was a self-service laundry place a few minutes away at a reasonable price.
Overall really enjoyed the experience, and it's really quite perfect if you don't mind the stairs.
