The apartment was clean and well-prepared, and everything was as described. The communication with hosts was very good and the check-in was smooth.
The location is excellent if you want to party but not that good if you want to sleep. It is very loud at night in the apartment (with all the windows closed) because of the many pubs/bars in the neighborhood. I don't recommend this location if you want a good sleep, especially around weekends. I was struggling for 2 hours to fall asleep and had to use headphones to finally be able to sleep.
The other thing that could be a problem for someone (wasn't really for us) is the fact that the apartment is on the 4th floor without the elevator and the stairs are very steep. I imagine it could be really difficult to bring bigger luggage up the stairs. The staircase is also very tight at some points.
