Room labels are not perfectly standardized. Treat the listing description and current photographs as the source of truth, then confirm anything essential before booking.
Single rooms
A single room describes sleeping capacity, not automatically a private bathroom, window, desk or a particular bed width.
Double rooms
Check whether “double” refers to the bed, occupancy or both, and verify the bathroom arrangement.
Twin rooms
Twin usually signals separate beds, but the available floor space and storage vary.
Small dorms
Ask how beds are arranged, whether lockers are provided and how quiet-hours rules work.
Shared dorms
Compare privacy curtains, charging access, luggage storage, bathroom capacity and any gender-specific arrangement shown in the current listing.
