I was impressed by the quality of the appointments, e.g., the cutlery, etc., and I never had any issues that I needed to have resolved.
My wife, daughter and I stayed for a week during August. The apartment gets very warm, and it's hard to circulate the hot air out. We opened both windows and the front door, but it still took a long time to cool down the unit. We were never able to completely close the windows while we were in the unit.
The closeness of the unit to three tram lines is convenient, but the price you pay is that a very loud tram arrives or departs every few minutes, including at least late into the night. Police and ambulance sirens were louder, though. Being used to city noises would be helpful.
The lighting in the main room also needs to be doubled. If I wanted to study a map, I had to lay the map on top of the washing machine in the bathroom to have enough light to see it clearly.
