Sheets, pillows, towels were clean, that is great. But really any other place than the most obvious ones like the main floor were quite dirty. A proper thorough cleaning should be done, under the tables, in the room corners, under the bed, bathroom faucet, etc.
Also both ventilation openings were black and the air coming in was not pleasant and very moldy. I have asthma, so that really bothered my throat and breathing, even though my stay was not during the humid season. Ventilation openings should really be cleaned, because the black moldy spots on the openings really do not instill confidence in the cleanliness of the place.
Air coming from the air conditioning seemed cleaner than one coming from the ventilation openings. Luckily we only stayed for one night. If I had to stay there for multiple nights, I can imagine that I would have more serious respiratory issues. So there are health concerns. Think twice about this place if you have respiratory issues.
The bed is extremely squeaky. If you plan to come there as a couple, you could get very uncomfortable with the loudness of the bed. They should just put in simple thin hard mattresses. That would fit the price category and still be a good and durable option.
The place is very good for the price, so that is cool, but they really need to clean it more thoroughly. Cleanliness should be the basic requirement, no matter the price.
