We checked in later than expected, as our flight was a bit late, but Sebastian told us he would leave the keys somewhere at the fifth floor and would send us a picture. Unfortunately, he had his phone stolen and the picture never got to us. We arrived there without knowing which one was our apartment or where he left the keys and with the host not answering, which was really unpleasant. Eventually, we found the keys and guessed the door, so we managed to get in.
Otherwise, the place was ok, very well located near the metro station, in a nice and safe area with plenty of restaurants.
On the day of our departure, we had our flight in the evening and we could leave our luggages at the apartment until we left to the airport, which was great.
Overall, our stay was ok and the place is a good value for money. :)
