Very cold experience, it's like being in a hotel without reception so you cannot even ask for clean towels/sheet, they give you lots of rules but you cannot open windows to change air nor you can control the heating.
If 1 or more guests stay for more than... say 3 days... I WOULD ASSUME you would allow them to receive clean towels/sheets, I stayed a week using the same towels, not the best experience.
Especially in these time of pandemic, being able to open the windows sometimes to change air inside the room would be amazing.
Heating control was not even working nor explained.
The pictures provided are just from a random flat, since you got 100s of those flats which is misleading when choosing.
In my opinion not worth the money
