    "Staff are nice and helpful. The check in was smooth and problemless. However water pressure and temperature wasn't great, and the soundproof wasn't too well. I was hearing door slapping all night from other rooms and the emergency exit. The hair dryer was located underneath the TV, but there were 2 water bottle completely blocking the view, I needed to ask the staff. Overall satisfied but a lot of small improvement can be made."
