Great interior of the apartment - cozy, homey, detailed - and was clean and well organised. It also had a great shower with hot water. The other big plus was the very convenient location - it is meters away from few of the main pedestrian zones and sightseeings. Also, the hosts had perfect instructions on how to get to the apartment.
On the other hand, the apartment is on the first floor, right next to a metal door that leads to more apartments and also a terrace (which is right outside the windows, so there is no privacy unless you keep the blinds on the whole day), and every opening/closing of that door is quite noisy and happens often during the day, but also at night time, so sleeping might be a challenge.
