The apartment in itself is nice and spacious, with an adequate kitchen and bathroom. We had issues with:
1) There is no parking and it can be very hard to find streetside parking nearby, depending on time day.
2) The heating is independent with a boiler in kitchen. That actually meant we could manage wartime restrictions. On the downside, the boiler was off at check-in (or we accidentally switched it off, the button is like the lighting switches) and through our stay it switched off 2-3 times with an Error 504. Took us a couple days to figure out how to restart it . No info on this was given at check-in.
3) The elevator is malfunctioning and/or access was restricted to us. As we were traveling with kids, a stroller and lots of luggage, this was inconvenient. The check-in guy seemed unaware of any restrictions and offered to take the elevator for the check-in inspection, which regretfully I declined - that would have clarified things.
