I stayed here for a month with no real problems at all. It's in a great location, very central with the subway and streetcars very close, though much of the city is walkwable from here. Wei is fantastic, really responsive and quick to help in any way he can.
It's probably not one for very light sleepers, as you can hear the neighbours quite a bit and the heating/AC is very loud. It's very compact but does have everything you need - Well stocked kitchen and the washer & dryer are a big help. Fairly clean in general, if not sparkling. All round good value and a decent spot to explore the city from.
