The apartment itself is spacious, modern and in a good location (also next to a Lidl). Bathroom was clean and living space was very spacious. The sofa bed was very comfy. Although we didn't get any pillows for the sofa bed, which would have been a bonus.
The apartment is on the 6th floor, and when we stayed the elevator was broken, it was horrible carrying 4 heavy suitcases up 6 flights of stairs. We were surprised that we weren't notified that the elevator was broken prior to booking, and probably would have cancelled if we knew this was the case.
Also the apartment building was going through some sort of construction, so each day we were woken up by loud drilling at 8:30AM. This was right outside our bedroom window, which meant that it was very uncomfortable to open the curtains as the workers could see straight into the room.
