There is mold in the bedroom ceiling and the sheet are very old, probably the owners old and used sheets. The shower is pretty disgusting and this place is in an area that is really bad with crazy people on the street and terrible access, with cars parked on both sidewalks so you have to walk in the middle of the road, and yes, a lot of garbage on the street on the way to the flat.
Btw, there is no smart lock as described, it's just a numbered padlock
