It depends how hot it is, our upstairs can get up to 40 degrees or more on the really hot days so when its like that it won't be cold but cool, otherwise it can be cold if you sit the temp down that low or if you have it on for a long time.
The kids rooms are smallish too so that helps also. We've been really happy with it cause it helps keep the room decent enough to have good night sleep, we do need to leave it on most night too cause once its off it heats up pretty fast. And we need to put it on at least 2hrs before bed to get the room cooler.
Also if your windows are wind out like ours its a bit harder cause you can't put the tube out without allowing hot air to re enter. If they're up/ down windows prolly will work even better.
I have 2 portable aircons - both De Longhi Pinguino & they are both *fantastic*. They are "real" airconditioners, one of them has a water boosted action & a tube that you use to vent the hot air out a window/door. The other is a portable split system, so the fan part sits inside the room and it's connected to the split system by a long insulated tube thing that you can feed out thru a window or door. It's very powerful and can cool a large space like a large l-shaped kitchen/family room area. It was quite expensive but a godsend, especially if you're moving from rental to rental. The split system is quieter than the other but obviously cost a lot more so there's a payoff there.
I can't think when it gets too hot so it's been worth every penny here - but it was very expensive to run both of them day & night during the big heatwave we had in Jan so I think I'll be a bit more careful with their use from now on.

When we were renting we bought a portable aircon. It was a refrigerative one with a tube you stick out the window. It was useless. We spent about $900 and got a very powerful one. It blew out cool air, but the unit itself and the tube got so hot that it all evened out. I read the manual and there was one sentence that said it wasn't a 'room' airconditioner, it was designed to cool a personal space within a room. It was also so loud.
We ended up taking it back and buying a box one and temporarily mounting it in a window. It worked so well.
