This place could be great, but it is not.
Positive things first: the layout of the accommodation is unique, functional and enjoyable, the bedsheets were clean.
On the other side the place has a terrible smell to it (smoke, mold, both?). It has moldy cutting boards, bathroom furniture and shower curtains. The toilet bowl is loose, even with my average 80kg ass i was afraid that it will fall over. Several lamps did not work. Some wall outlets are loose.
Charging 50€ for cleaning, is cheeky considering the dust and grease layers all over the place.
Also 30€ service fee for an annoying amount of reminders to check in on their external page and to check out on time are bold.
And on top of all it is located in a dirty, dodgy back-alley.
We would not revisit this place for free.
