This apartment is very appealing and found exactly as in the pictures.
Heating works well, kitchenette equipment is very basic.
The clerk service by the next door hotel (same management) is available 24/7, they do check in/out and are very helpful.
The front and apt doors are new, super heavy and safe, nice feature.
Yes, it is an old building which implies its sound insulation is barely non-existent and I had read reviews before, so I was aware. Nonetheless, depending on the other guests it may be super loud as you sleep close to the ceiling and obviously not everyone is careful with the heavy doors, despite the plentiful requests of the management.
I would stay here again, good value for money and good location to get around too.
