We stayed in the apartment for six days. It is located in the city center & really close to the old town; everything is in walking distance. The apartment is cozy and spacious, heating and hot water 247 and the host was very helpful and responsive. However, there were some elements that could be improved in the future: 1) the mattress was not comfortable, 2) the place and especially the bathroom could be cleaner, 3) the closet was quite small and the entrance was messy and 4) there was garbage in the common area (from other apartments of the building) which was not picked up till the last day.
Overall, I would recommend staying in the apartment especially because of the location, but certainly there is room for improvement.
