It stated that checkin was at 15:00. When I arrived at 16:00 the cleaning ladies told me to wait as they still had to clean the apartment so I can wait in the living room while they do that.
The apartment has a lot of open parts that face the interior of the building complex and is barely insulated so you can hear all the neighbors TVs etc. It was very loud and hectic at all times.
On the second day there the neighbors got into a loud fight throwing things at the shared (and very thin) wall and cursing at each other.
To Juub's credit I informed him of this, asked to shorten the stay because it just wasn't a place I felt safe to relax in and he agreed on the spot with no issue.
It is in a great location, but I left 3 nights early.
