Maybe if you can spritz the leaves during daytime just to help humidity aspect, but make sure run the fan, to decrease fungal attack. It is a very tropical plant usually grown as an outdoor plant that thrives in lots of humidity and lots of sun. In its normal habitat humidity levels of 70% to 100% is what it likes. If temps are quite warm and grown outdoors, it can take in a lot of water. so grown indoors all those factors are much more diminished. If you can raise your apartments humidity that will be good, but watch out, you might end up with molds too, and I do not know how much humidity you can tolerate indoors too.
Your temps are good, but indoors, with dry air and not much good ventilation, it will suffer a bit. But hopefully it should bounce back when your temps return outdoors in the 70's and higher and move it later on gradually to a much more sunnier side of your area. It will need the sun to make good blooms too.
