My partner and I stayed in room 119 over New Year's Eve (3 days). Unfortunately, there aren't many pictures on AirBnB, but if you coogle Premier Suites Plus, you'll find their website, where you can find more photos.
The apartments are smallish but nice, providing everything you could need for a short stay - or so we thought. In our case, the room did unfortunately not fulfill the advertised features as, on 1.5 days, we had no warm water (there were some issues with the boiler) so we had to take showers in the public changing rooms in the basement and, additionally, the dishwasher was not working during the whole stay. The incredibly friendly staff tried to fix it, but it wasn't possible.
We have thus requested a partial refund because of this but haven't heard back from them yet.
We do want to stress though that we might've simply been very unlucky with the room - the staff were amazing and other than the amenities not working, we did enjoy our stay.
