The apartment has limited ventilation with the main bedroom having both
the only access to balcony and the only A/C. The second bedroom has a thin wall with the neighbours and we were unfortunately troubled by a washing machine going at all hours (it is also a rental so diff out to control the customers there). It’s also small and has no ventilation at all… the fan provided we had to lie on the side because it was noisy and had to put it outside the room in order to get fresh air in and leave the door open.
Overall it’s not a terrible place by any means - if you want a one bedroom then perhaps look at it, but the second room is not for comfortable for adults or children who are light sleepers.
