I would take the small room. Small rooms are nice and cozy. The privacy is definitely a plus, and your own bathroom. Sounds like you should just take the small one!
Here's the situation: My room is HUMONGOUS! So big that it's almost overwhelming. I've got a 42 inch
TV on a table, a large Piano Keyboard, two circle chairs, a queen sized bed, two side tables, a dresser, and a desk in the room, and there's still room to put more things in there. It's also freezing cold in there. I have no privacy, everyone just walks in because there is not a door. I also have to share my large bathroom with the whole family. I really don't spend much time in my room. The bedroom upstairs is smaller, but it's really nice. It always seems to be the perfect temperature in there. There is a couch up there! No one ever really comes up there, so I have more privacy. There is a door (hallelujah). There is a bathroom up there that I could use by myself. However, most of my things have no place in the bedroom, because it is smaller. This bedroom is creepy at night, but I kind of like that. When I wake up from sleeping upstairs, I always feel so refreshed and ready to take on the day. Aaaaannnnnddddd (drumroll please) I can bring food and drinks up there! I think it'd be a good move, but I'm not exactly sure, because it is a lot smaller than my room. What do you guys think?
