AITA AM i the asshole for wanting to rest? Or is it my mom?

They are festive dates and my brothers with their partners arrived at my parents' house in Marbella, I arrived first so I always have a room with all my things when I arrive because not long ago I lived with them then my mom told me as soon as I arrived this is your room, we only have one problem when they all arrive we are not going to enter, so I agreed to say that I slept in the living room without problem even knowing that it is uncomfortable but so that the rest have their comfort. My mom told me that she could put a mattress in her room but I said no problem, it should be emphasised that I gave in to lend my room to my brother and his girlfriend for 15 days.I've had several bad nights already because I've been very cold due to lack of quilts or because my stepfather and my dog have been making noise since 7 am in the living room where I sleep. Without any mercy that I'm sleeping there, and other people. Today I was already extremely tired and I went to take a nap to my mom's room while she was not there, I took a little nap and she came to her room to make a lot of noise knowing that I was there and my bad night. I asked her for a favour if she would let me rest a little longer without noise because I needed it and yet she told me no, that in a couple of days that they all left I would have my room and my tranquillity, even if it didn't cost her anything to leave me her room for an hour or two more so that she could rest from so many bad nights on the couch. Am i the bad guy? Should I be uncomfortable for a few days until they leave?
