I liked the apartment very much. It's very nice, clean and cozy. The location is excellent, right next to the main square in the old city.
However, I didn't find nice to charge 20€ to leave the bags for a few hours in the apartment. So far, all the hotels or apartments I've stayed in, no one has charged extra money for that.
Overall, I definetely would stay in this apartement again and I recomend it.
