Loft: free housing and utilities; no clear downsides

Diner: infinite free food; no clear downsides

Hotel: free temporary housing; unclear limitations on length of stay; implied risk of Shining-style shenanigans from guests

Shop: scope of shop stock and allowable "purchases" unclear; potentially infinite garbage

Forest: infinite free food; guaranteed restful sleep; time freezing outside while passing inside presumably causes you to age and die at least 33% faster relative to those outside if you sleep there every night

Library: access to knowledge in "known universe" presumably limits scope to things that a human of earth already knows; learning requires unassisted research; similar temporal risks to forest coupled with explicit risk of being lost in extra-planar space.
