There are many great things about the apartment: the location is absolutely perfect, right next to the main attractions and restaurants but still in quiet area. Also it is very large and it has everything you need. However, there are two main things which were disadvantages for us: first, there is a sewage-like smell which seems to come from the bathroom, and which spreads throughout the house even when keeping the doors closed. This is probably typical of the area since the plumbing is old. Secondly, although the apartment was very quiet during the day, the neighbours were noisy talking in the early hours of the morning. In the end we moved to a different room and this was better. This could be a problem if you are a light sleeper like myself.
Also, note that there are quite steep stairs to come up to the apartment.
