I booked the apartment for 4 weeks. The apartment was clean by the look of it. However, the bathroom had a terrible sewage smell, so bad that you need to hold your breath. I raised the issue with UWS and they acknowledged that they had the same issue before. They sent a plumber over and he put some chemicals down the drain, which has improved the situation. However, UWS wanted to charge me $250, and claimed that we have caused the sewage smell, which is completely unacceptable. UWS has raised this to dispute resolution, which is still pending. I own a property and I know that this sort of smell comes from the water sealing failure in the sewage. UWS and the landlord apparently does not intend to address it properly as chemicals will only mitigate the issue temporarily. Besides, the apartment is situated on a lower floor and the kitchen exhaust coming from the Korean restaurants downstairs constantly pollutes the air from 12pm to 7pm. The belcony door is essentially unopenable unless you wish to live in the smell of grease all the time. I will not be going back and I suggest future guests to reconsider their options.
