Shanshan is an excellent host, who responded quickly and clearly to questions and provided very useful information and advice to assist those travelling into HK from the airport. The self check-in process was simple and effective as was check-out on departure day. Overall communication was excellent, providing confidence in the booking for those still nervous about using Airbnb.
Onto the apartment. Location is good for access to the MTR and there are plenty of taxis passing by. The street is one away from Lockhart Road - a busy nightclub/bars area. However, this can easily be avoided and the street of the apartment building is much quieter with just a couple of bars. The apartment is small but clean and secure. There are two small bedrooms with small double beds. The bathroom is also very small (basically a shower unit and toilet), although I think this is very common for Hong Kong. We were two single travellers (both not tall) so this was fine for our needs but I would suggest that for a family, or for anyone over 5ft 10 (178cm) in height the bedrooms might be a squeeze and bathroom capacity a bit constraining.
Other positives include the excellent air conditioning (a must in HK) and excellent broadband wi-fi. We had no issues accessing the building or apartment.
Overall, we were perfectly happy with our stay. A little more room would have been nice, but, as noted, the standard in Hong Kong does seem to be for smaller apartments. And, as stated, Shanshan is an excellent host, which is always very important in using Airbnb.
