My experience with Yin during my 5 month stay was both positive and negative. Yin was very efficient and quick to respond leading up to my stay and gave good recommendations on things and amenities in the area. I was told before booking that I would have the apartment to myself for the first three months while Yin was away, however when I arrived I was introduced to another tenant who shared the space for the duration of my stay. Yin and the tenant had an arrangement where he would be charged less rent to clean and take care of the apartment, which he did with little issues. At the end of my stay Yin made a claim for additional payment against me for broken/missing items which I was neither aware of nor responsible for. I have recommended to Yin to speak to the other tenant about this, and am currently disputing this through Airbnb. This was an unfortunate end to an otherwise quite amicable relationship.
If you are staying in the apartment while Yin is away, i recommend taking photos of the apartment upon check in and requesting an inventory of items in the apartment so that you can be prepared should any disputes arise after your stay.
The apartment itself is quite spacious compared to what you'd expect in Hong Kong. Really great location and nicely decorated- feels quite homely. The 5 flight walk up and lack of functioning air conditioning in the living room and bedroom makes it a little uncomfortable during very hot days. Overall it's a lovely space to stay, especially if you want to be close to all the bars and restaurants.
