First of all, Pauline was extremely hospitable. She was very quick to reply all our questions beforehand, and arranged to meet us at the unit on the first day to personally explain all the details of the house. 5 stars for that :)
The house itself was clean and cosy. There was a very nicely-designed living space with a comfortable bed and sufficient ventilation. The bathroom is extremely tiny though, so do note the following details: (i) the kitchen and bathroom share a sink, and (ii) you bathe in a space that holds the toilet bowl as well. If you are fine with that, no issue. A bit of a walk to Sheung Wan MTR (maybe about 10mins? In cold weather it's quite good to walk more), but the neighbourhood itself is very quiet and relatively near food joints (a few minutes' walk away).
