It will be freezing,
You need at least 10 people living there to make it worthwhile,
It's probably grade 2 which means you cannot change anything without written permission,
It's freezing,
The worry of a leaking roof, and anything else degrading on the property, isn't worth the sleepless nights,
Imagine the heating bill,
Imagine the maintenance of each room,
Too many negatives even if the 3 people's you know well visited often.
