First of all, I didn’t expect a basement room but that itself is still fine. You had to deposit the keys at the reception when you leave the hotel, but there was no verification of room owner by the looks of it. All we had to do was say a room number and we would get the key. Not sure if this is safe.
Additionally, while we were still inside the room in the morning, staff would just come and open the door without knocking or stating their purpose, which was totally unacceptable for sake of security, privacy and respect!
