I wouldn't want to date any of the mane 6 but as for whom I'd like to crash with if I was staying with any one of them I'd probably be at Twilight's place. All of those books, and the peaceful quiet environment of the library with a little servant to bring me the books I'd like to read. It wouldn't be all that bad I'd say.
Which of the mane six I'd crash with----let's see.
1: Rarity wouldn't be to bad to live with but you'd have to mind your P's and Q's and above all good manners is #1 under Rarity's roof.
2: Twilight would be another great place to crash---it would peaceful in there.
3: Applejack is also another good place but you'd have to get up when everypony does----sleeping in would be rare on her farm.
4: Fluttershy I would have to pass on---I have a house with 5 dogs (5th one I'm doggysetting until me Dad's friend get's back in town) and it's annoying sometimes.
5: Rainbow Dash would be awesome to crash with, soft comfy beds, you get a great view of Equestria and you're on a cloud.
6: Due to Pinkie Pie's landlords having babies---I'd pass on that.
