SIL rent

So my husband and I are currently staying with his sister (my sil) . Her son is also our godson, it's been a year since his baptism and I was going to share some pictures she had posted, well I find out she has blocked me from fb. We are currently having problems with them while staying there because she has the a/c full blast and I have an 8 month old and his been sick since we moved in. We've told her nicely if she could put it down some and she did but she puts it back on at night. Also they don't sleep still 12 or 1am and her kids (ages 4& almost 2) are always screaming, crying and throwing things and constantly knocking on our door and they just sit there saying NOTHING. It wouldn't really bother me if I didn't have a baby, but he can't seem to sleep with all the noise they make and my husband get up at 5am to go to work. We are moving out this weekend and I told my husband that when I leave I don't want to go back not even for parties or holiday's. Oh I almost forgot to mention that she doesn't like my son.!

Am I being shady for not wanting to do anything with her and not wanting to go back to her house...
