OP I had the same issue (sideways sliding windows and all) and bought two Hisense double-hose 8,000 BTU units just last summer. They worked perfectly to keep our 2bed apartment cool. [This is the exact unit.](https://www.amazon.com/gp/aw/d/B0D94WL44L?psc=1&ref=ppx_pop_mob_b_asin_title)
I am actually looking to sell one or both of them soon, as we're moving to a place that has a heat pump. Wasn't planning to list them until closer to summer, but message me if you're interested.
Not an HVAC tech.
If you rent and can’t install a window unit due to being in a tall apartment complex or just lease restrictions, consider a dual hose portable AC unit (don’t bother with a single hose portable AC).
Here’s one I got from Amazon: [Hisense 8,000 BTU Portable Air Conditioner with Dual Hose & Inverter](https://www.amazon.com/dp/B0D94WL44L?ref=cm_sw_r_cso_cp_apin_dp_JH13RR1ZBK9E44FSYMVB&ref_=cm_sw_r_cso_cp_apin_dp_JH13RR1ZBK9E44FSYMVB&social_share=cm_sw_r_cso_cp_apin_dp_JH13RR1ZBK9E44FSYMVB&csmig=1)

I bought a refurbished one (like this one pictured) for $250 and it’s awesome. It’s quiet. It kept our living room, bedroom, kitchen and bathroom cool when our main Hvac went out in our 1400’sq ft house and we couldn’t get it repaired for a week because of a heat wave (HVAC workers were working overtime).
I drain it every 2 weeks and—even when it’s averaged 95 - 100 degrees every day—it only produced 1/2 cup of water in 2 weeks (so i really didn’t have to drain it). The single hose portable a/c units have to be emptied daily usually.
It has two hoses that connect to a panel that goes in your window—so be sure that it will fit your window. Also, it comes with insulation for the window but I bought some thicker foam strips for a few bucks and some HVAC tape and even bought some insulation for the hoses. However that’s not necessary.
Anyway… mine is amazing and we kept it in the bedroom because I hate being hot at night.
Also, I recommend this video before buying because it helped me know the basics of installing and what to expect. FWIW I’m a 48 year old overweight woman and I did it all myself in about 30-40 minutes.

I bought this one last year. It's a beast. [https://www.bestbuy.ca/en-ca/product/hisense-smart-3-in-1-portable-air-conditioner-w-casement-window-kit-w-wi-fi-12400btu-sacc-10000btu-only-at-best-buy/17459076](https://www.bestbuy.ca/en-ca/product/hisense-smart-3-in-1-portable-air-conditioner-w-casement-window-kit-w-wi-fi-12400btu-sacc-10000btu-only-at-best-buy/17459076)
I have it to cool about a 350 sq ft space, in high humidity environment-using it about 2 months on 77 degrees farenheight at lowest (outside temps 90-100 degrees). It is a room I do not really use now, but want to keep cool; because room radiates alot of heat through large glass doors. I never use it on dehumidify, because I do not want to hassel with draining it (not had to on a/c mode-also read heat pump mode could require more draining - so I got a/c only model )
I also cut out insulation board to reinforce plastic window hose mount, matching size of needed plastic window hose mount; taped together with aluminum tape. It is only 8k btu so probably won't cool very large space, depending on insulation, and ambient temps. Also, must insulate hot side exhaust hose for better efficiency (get flexible cover on Amazon ; not the stiff ones); or wrap with some type of insulation.
This is inverter model, so I do not know how much it will vibrate, when compressor revs down to save energy-may need to place on mat to subdue vibration-especially on bare floors. One thing about the in window placed single inverter units (talkin about different models that actually place inside open window) that I did not know about was the vibration caused by the compressor reving down, and causing low frequency vibration-travels through widow and even walls. In this respect, this portable A/C is probably better, because much easier to stop vibration, by simply placing portable unit on a thick mat.
