"Do not recommend for non-smokers. Cigarette smoke leaks into the non-smoking room.
I cannot tolerate the smell of cigarette smoke as it causes me severe headaches, so I made sure to book a non-smoking room.
However, after getting into bed at night, I noticed a strong smell of cigarette smoke drifting into the room intermittently. When I checked to find the source, I discovered that the smell was leaking from the gaps around the maintenance hatch (access door) located near the floor. It seems that smoke from the smoking area or plumbing space is getting pushed directly into this room due to structural or ventilation issues.
Since I only realized this after getting into bed late at night, and figuring other rooms might have the same structural issue, I gave up on asking for a room change at the time. As a result, it was a very disappointing stay that left me with a bad headache.
If you are sensitive or allergic to cigarette smoke, I highly recommend looking for another hotel, as booking a non-smoking room here does not guarantee a smoke-free environment. I strongly hope the hotel takes measures to completely seal these maintenance hatches to prevent odor leakage."
