If you do book, DO NOT walk to the appartment from the train station despite what you may be told to do. Depending on which part of the station you alight, it may be a 20 minutes walk. Worse still, the uphill and 150 stairs makes you feel like it's a staircase to hell. Take the tram please.
It's not 2 toilets, but 1 toilet with 2 doors. The doors are transparent/translucent, so you would be able to see inside the toilet quite clearly. All the more awkward given that the toilet bowl is right in front of the door. Do note that the washing machine is not in the appartment.
Other than the above, check in was hassle free, apartments are clean.
