New hotel.
The bedroom window was completely blocked. I requested that it be unlocked (as it only required removing one screw), and I have a phobia of locked rooms, but the staff refused, arguing that young people were jumping between balconies. They argued to me that there were many hotels that no longer open their windows. And my answer was that even if it's just for ventilation, the windows should be opened. Although some hotels have fixed windows, they usually have a double flow system, I doubt this one had it.
