Cuba cost of accomodations
The best value accommodation in Cuba is in casas particulares – in rooms in private houses. Here a double will cost around $20-30CUC (Cuban convertible pesos – $1CUC = US$1), though in Havana it can be a bit more than that.
Hotels will be more, between $60 and $210CUC or more at the all-inclusives, so you’re unlikely to get a decent hotel room for less than about $50 anywhere, and it’ll be higher in the more touristy places.
Hope that helps.
