So, i don't know why it's called luxury, but it's far from it. First bad impression asa you step into the building. Dirty in general. In the actual flat: windows look like never have been cleaned (covered cobwebs as well). Shutters or blinds dirty. Non of the windows opens or closes properly. Sofa totally ruined, scratched by cat or something. Door in one of the rooms properly broken, there's no even a lock left. And so on.
Maybe it's ok when you are 16 and having party with your mates, but for nothing else.
We booked for 3 nights, but did not stay even one. Found ourselves hotel on the next street and left.
Would not recommend.
