Overall a very pleasant place to stay. The rooftop and view are really what stand out for this property - amazing views over the harbour. The apartment is a typical HK space (ie, small rooms) but has everything you need, including a fully stocked kitchen, drinking water machine (hot and cold), etc., though there are plenty of restaurants nearby so we ate mostly take-away.
Ray was very responsive, and flexible with check-in and check-out times.
The listing is a bit unclear about sleeping arrangements - there is really only one bedroom, and no space in the office for a bed, but the sofa in the LR does indeed fold out if you need another bed.
I would definitely recommend staying here, especially for the rooftop.
