The rating turned out to be 4.5 by summing the individual categories and taking the average.
Check-in is very bad, the parking is not "difficult to find", it is non-existent (unless you want to walk 0.5 miles). It might not be a problem if you have only a backpack, but it is a big problem if you have at least 2 bags. Check-out went better, it was easier to park with emergency lights for 10 minutes and move away compared to a longer 30 minutes parking for check-in.
In other criteria it was better than similar Airbnb for the same price. The apartment was bigger (around 350 sqft compared to common 200sqft rooms). There was a small kitchen in the apartment. The table in the room had enough space for multiple devices with sockets nearby. There were no barking dogs and the walls were good enough so that you would not hear the neighbors. It was noisy from the street, but at least it could be mitigated by closing the windows. Access was without keys, so you only need to remember 2 numbers instead of carrying the keys.
