1. Could not really open the curtain unless you want others to see your room right away.
2. The mattress was really stiff like a stone.
3. A bit Far from subway stations, had to walk 10-15 mins with my suitcase.
4. It's a relatively new building and extremely clean inside. The staffs were kind and helpful.
5. There were no power outlets near the bed in my room. (Couldn't use my laptop on the bed while charging)
6. When ventilation fans were on, they made really annoying high-pitch sounds that bothered me a lot during the night. (there were no windows in the bathroom and toilet.)
