Don't ask here, take measurements of your windows and check with your local appliance center and get a recommendation. If you have space outside and stray cats and rats aren't much of a problem you can get a split-type inverter. It puts most of the stuff on a unit outside so noise is significantly reduced. I don't know local prices in your area but over here Panasonic and LG already have some of these for less than $500. Back in 2010 when I replaced the window-unit in my bedroom (and moved the old one to replace the busted up one in my home office) I paid $400 for it (Panasonic; prior to that we used local brands using Panasonic Kompressors). It also has a boost mode so for the first fifteen minutes it runs at full tilt (that you can't activate otherwise; this is kind of like nitrous oxide in a dragster, sort of) to speed up cooling the room, then goes into its normal performance parameters. If I had to buy one now I'd cough up the extra $100 for the split inverter unit and a little bit more for the installation fees.
Oh and depending on where you are there are other form factors. My brother in CA uses this thing on wheels that looks like an overgrown R2-D2, then it has a tube that you stick on the window sill to suck fresh air from outside. Advantages are it doesn't drip, but from my own skin's evalation his guest room in CA during July can't get colder than how my Panasonic unit cools my bedroom here just north of downtown Manila in May. Over here if I forget to set the timer and pass out I'll absolutely wake up at 4am to empty my bladder and/or to put socks on (assuming I don't have to get dressed for work).
