Clean? NOT, mold in the tub. You get yelled at if you open the windows, because you might break them, not all of us are incompetent idiots and can close a window without ripping the bottom off. This too is a result of poor maintenance, if you lubricate the sash and operate the unit then it will go up and down. Not everyone wants to sit inside with the ac blowing mold spores throughout. Not every unit has a balcony nor a slider, maybe those you can open but DO NOT TOUCH THE WINDOWS. My entire family does not recommend this facility. The other posts must be owners trying to increase their trading power or rent their units!!!!!!!!!!
