It was a good stay as the location is near to my office. The unit given to me was also a brand new one, so I had the privilege to use all new stuff. One drawback of this is that the room was so dusty, I could see the dust flying everywhere when I just came in.
The unit has a quite bad air circulation. Since there's no window, it can be very humid, so it won't be healthy to stay for long, especially if you spend some time in the room.
Generally, the facilities are great (with washing and drying machines). It would be great for a business trip or to bring family!
