I am so glad that I no longer live in my old apartment.
It wasn't a horrible apartment, mind you. In fact, it was fairly spacious. However, there was virtually no air flow around the building, thanks to the apartment buildings beside it. That made it oppressively hot during the summer months.
I got myself a portable air conditioner, but it didn't do a great job -- and it always drove my electric bill way up.
Even now, I have to spend quite a bit on my electric bill, thanks to the oppressive humidity. I'm trying to avoid that, but sometimes, I feel like I have little choice in the matter. I need to be able to function, and it's incredibly hard to do that during the summer.
