The apartment was very nice and cozy. Everything was clean and in good condition. The views over the rooftops are very nice. The kitchen area is small, but has everything necessary: pots, pans, water heater, etc. No microwave for those that are into quick-food, but that wasn't a problem for us.
The location of the flat is very good. There are numerous bars and restaurants within walking distance. There are metro stations nearby for those that travel by public transport. The Central station is a 20-30min walk away through the city center, which was a nice walk to take on the first day to get to know the city. Otherwise, the metro also takes you to the Central station.
During nighttime, there was some noise coming from the streets, but it is quite expected from an apartment located in such a central location.
What came to us as a bit of a surprise (probably didn't read the description and the reviews clearly enough) that there indeed is no door or wall to the bathroom area. In practice, there is a direct line of sight from the bed to the toilet seat. It's not world-ending, and we managed just fine, but something that fellow travelers should take into account.
