Open since 2022, every room at Monaco’s cutest—and usually least expensive—hotel has a sea view. Regular double rooms aren't large (but the entire country occupies 202 hectares/less than 1 sq. mile, so little wonder). But they do come with king sized beds, free coffee at reception, and the priceless harbor panorama. Nine of the rooms have private terraces, which would cost a thousand dollars anywhere else. Breakfast is served on the top floor terrace.
