The room was really small (arround 4 m2), much smaller than it looks on the photos. The price (almost 7000 HKD per month) is pretty insane for what you get, even in Causeway Bay.
I highly recommend that you find a way to see the place for yourself before making a reservation.
The apartment was a total mess, thanks to a couple that is living in the flat I rented for about a year, but that's just bad luck I guess.
Anyway I didn't feel good at all in this flat and I'm glad I left it.

I gotta say however that Ivy is very eager to help if you have any problem.
