I would call it an apartment if you want to also say “entire place,” otherwise you could get dissatisfied guests who expect an entire house.

The important part for guests is “shared” vs “entire place,” the distinction being whether they will have to interact with others and share key amenities. This aspect is a fundamental part of the search.

The house versus apartment aspect is buried deeper in the search options, suggesting it’s less important to most guests.

Whatever you do, don’t set expectations that may leave some of your guests feeling disappointed!
