Sadly didn't quite meet our expectations.
Communication with the host was really easy, they were very nice and always quick to reply. Check-in was even possible a coupe of hours earlier than expected.
However, the apartment itself was a bit underwhelming. The size was adequate for two people, but it was advertised for three which would have gotten a little crowded.
Unfortunately, the apartment was simply not clean. On the floor there was dust, hair and fingernails and there were cobwebs on the ceiling and the corners of the rooms. Except for quite a bit of mold in the shower, the bathroom was clean, but the bathroom door was broken, so the host had installed a small see through-curtain instead. The equiptment in the kitchen was minimal and some of the dishes were dirty.
On the upside, the location of the apartment is unbeatable - all of the major sites in the old town are located within a 5-10 min walking distance so you won't need a ticket for public transport. In the night it can get a bit loud on the streets, especially on the weekends, but the host kindly provided us with earplugs.
