Unfortunately we were not very happy with the apartment, which is in a bad base condition including lights not working, damaged furniture and the already mentioned window handle. Beds were uncomfortable and the air was unventilated especially in the corridor, which is also very dirty and damaged. The street is very loud and many sirens can be heard all over the night even with closed windows. Taxi driver told us the area is also not very safe - we did not have any issue so not able to confirm.
Overall these points let us feel not welcomed and unhappy with the stay in the apartment. We were lucky that weather was so great that we were able to spend the least possible time in the apartment.
If you are not very picky on the mentioned points and are looking for a place to stay very central, go for it.
