The room has a strong musty smell and it didn’t get better even I turned on my air purifier. There’s a dehumidifier in room but it seems not working much at all. The AQI is very high (over 170) according to my device. I guess it’s because of the bad ventilation. Overall the room is neat and tidy, it is worth staying for this reasonable price, only the smell and bad air quality made me feel unwell during the stay.
