Very convenient place, about a 5 min walk from a metro station (ShuangLian 雙連), maybe 10 minutes to Ningxia night market (寧夏夜市).
There is a 7-11 is just across the street, with a lot of cafes, restaurants in the area.
A very clean and organised house, and a very cozy room to yourself.
I was only there for less than a week and hence didn't get to talk much, but Huaihui is a very approachable and helpful host based on my limited interaction with her.
Great experience and place and will recommend to friends.
