The communication with the host was easy and we were even allowed to check in earlier. The location is good if you are interested in night life and don't mind the noise, plus it's very central so you can reach most places on foot.
The host warned us about the apartment being noisy at night due to the many bars in the area before accepting our reservation. We were ok with this as we knew this was the going out area, but once in the apartment we found most of the noise was coming from our neighbors (it seemed to be an Airbnb as well, and they were partying every single night), so the bars were the least of our problem. The neighbours airbnb has a terrace at the same level as our apartment and the window of one of the room was directly facing it. This means we had no privacy at all if we opened the window as then the neighbours would just see into our room. It's pretty hot in summer, so a closed window is not bearable at night, but once open the noise from our neighbors wouldn't let us sleep at all.
Additionally, the pictures look much better than the apartment (very old furniture, old and thin mattress -we could feel the springs-, some mold in the shower ceiling...), if it had been cheaper we wouldn't be able to complain but it's not precisely a bargain for what you get...
