Yin's place is very nice and clean. It is very central and in walking distance to the centre and a lot of nice things. The city itself seems quite safe too.
Yin is a very responsive host(she was out of town while we were there). Usually had answers within a few minutes.
The flat itself is pretty basic. Good wifi, smells good, has everything we needed and a comfy bed and good pillows.
Haven't been in other apartments in Hong Kong so I don't have any comparison. My friend and I really enjoyed our stay though.
Two blankets would've been nice but not necessary. A sheet did the trick too. Probably could've asked her for one if we really needed one.
Yin had forgotten a little food in the fridge. It was very nice of her to let us eat it
