Pinguino PACEL112CST

that's a high estimate. We live live in a place with west and east facing windows, so it can basically become a greenhouse in the summer (sun all day). We also have a 'Stroad' on one side, so opening the windows during the day can lead to really bad air quality in the apartment. our portable unit was 450 and it cools 55 m2 to about 23-24 degrees in a few hours really well.

It's a De'Longhi Pinguino EL122. Even now they're like 650 on Amazon but I bought ours last year in January for 450. It also has a 63db 'whisper mode' which is very very quiet (at least for an A/C) I really don't think you need to spend anywhere near 1000 to get something good.

We shamelessly bought a portable one here in Switzerland, De'Longhi Pinguino, pretty good.

My De'Longhi was still going fine when I put it out for hard rubbish after about 20 years.

I love Black & Decker. Used to love Pingüino when Costco sold them.

We used a portable refrigerative air con temporarily (with removable window kit & tubing), which did the job for the master bedroom when we had a newborn (waiting on the ducted installer).

Pretty sure ours was a Delonghi, but this was many years ago - so there could be better options out there today
