There were renovations and construction taking place in the adjacent apartment, which is actually the other part of a "split" apartment. We were woken up every day by very loud drilling and hammering noises, which sounded like they are coming from inside the apartment. The host unfortunately did not bother to update us about the renovation in the description or in the private message after we booked, even thought it was the host who was doing the renovations. We would have never booked the place had we known.
Apart from that the apartment looks very nice, a lot of light from large windows, the shower is very good, the mattress (bed) is a little hard - if you prefer a soft mattress. The curtains let light inside, if that bothers you in the morning. The location is good, close to the old city and the main things but not in the middle of the old city. The street itself is not noisy, and the apartment has a two-window noise isolation (but that did not help with the construction noise)
