We had lovely stay at Xiong's apartment.
We felt like at home. It is comfortable, tidy and clean.
A bit far from the centre but perfectly fine to commute at any time and after a busy day it's great to have some quiet place to stay.
Make sure you arrange with Reina (the neighbour) to open the door for you.
she was also lovely. Flat doesn't have a hairdryer so she let us borrow hers.
