I stayed in Youth Hostel before in China, and I was very impressed with these services. Therefore I choose the YMCA when I go abroad alone.
The servicers are very nice in this hotal. The guy gave me a detail route when I wanted to go to the mission bay. He found a bus route in google map and proactively printed it for me, which inspire me deeply.
Although is a little small, the room has a freezer, a electric fan and a heater. A disadvantage is that there is a poor acoustic partition between my room and the street, but I still feel very sweet and relax.
In general, the hotel is very clean and has great facilities.
