I just spent a week at Shanshan's place in October 2019. The location was in the heart of Wanchai in an area with many good bars and restaurants. The protests were/are still going on in HK but fortunately they were not active in this vicinity during my stay.
Communication with Shanshan was excellent before, during and after my stay. The check-in was quite simple and efficient. Shanshan was quick to answer any questions I had.
As for the apartment itself, it was great. The place was spotless and had everything I needed for the stay. It has been remodeled a bit from the pictures in the listing. There is a ceiling fan in the living room now, which is a nice touch. All the switches are clearly labeled so there is no guessing about which switch controls what. This was a nice touch. The AC worked well and cooled the place quickly. The bathroom is a little on the small side and a very large person might find it somewhat confining. This is not uncommon in HK as the spaces are generally a little smaller.
I would definitely stay at Shanshan's place again if circumstances permit. It was a good experience overall.
