Positive side:
Communication is really good, Hui responds as soon as he can.
Location
The owner is super-friendly
Negative side:
It is loud, but do not forget that you are going to live downtown, hence it always will be loud, drunk people and you can hear the steps of the neighborhood.
I don't understand why sometimes the bedroom smelled like a canalization, maybe because water pipes are located in the room's window
Cleanliness. There are burn marks on the kitchen furniture, but if you plan to stay in the apartment only for nights, it is ok
I'd recommend providing a coffee for guests, as the apartment has a coffee machine, but no coffee. It is pity, especially if you are planning to stay for 2-3 days.
