Dongmei is incredibly welcoming and accommodating, the room is well-furnished with good quality furniture. There were also fruits, water, basic breakfast. Inside the room, there is also a Microwave, small fridge which was very handy and convenient. The room is very clean, the location is wonderful. Although we heard from people that there is a bit sketchy area nearby, as long as you don't walk outside after 10pm for whatever reason you have, I think it is a wonderful location. Quiet, safe, and quite close to downtown SF (takes 15mins by Uber-ing). The wall is a bit thin as you indeed can hear everything from the rooms next to you, it was mostly okay for us as people next to us sleep early.
For the price we paid for this room, we are super satisfied and felt home, we will definitely come back to Dongmei's place when we visit SF next time.
