The hotel was very dirty including rooms, bathroom, halls and smelling terribly like a dirty public washroom.
We complained a lot and finally after couple of days they changed the room to an upper level and promised to fix the vents and clean the room. Apparently, the new management team plan to renovate the rooms and make lots of changes. I found him trustworthy and make sure if you want to chose this hotel the renovation is done. Then perhaps you can call it a 4 star hotel.
