The prices of some things vary according to the provinces. That is important to take into consideration. Speaking for average tourism, a night in Havana can be between 15 or 35 cuc (1cuc = 1USD) depending on the season. The high season is from November to March sometimes it extends a little more. In low season you may be able to find a room for up to 10 cuc but the lower the price lower is the quality. This price fluctuates more or less the same throughout the country, although in the capital things will always be more expensive. Then putting an average price of accommodation, example 15 cuc for 7 days = 105 cuc (approximate, he highlighted that because in high season it can be the minimum 20-25 cuc) Most rental houses offer breakfast for 5 cuc, a meal with a drink included can be between 10 or 12 cuc per person. There are cheaper places, but I do not recommend them because the issue of water that Cubans use with us is fine, but for visitors I do not recommend that they drink water anywhere that is not bottled, that they buy it. The liter and a half knob costs 0.70 cuc. So making price 5 breakfast, 10 lunch, 10-12 dinner; between 25 and 30 cuc taking into account the water, for 7 days = 175-210. So, calculating 105 + 210 = 315, but it is only a basic estimate without counting on drinks or purchases that can be made outside the accommodation. For transportation and alcoholic beverages keep read. Approximately 800 cuc more or less a minimum price (With detailed transport below). If you add outings to bars and some extra taste ... then it increases the bill Of course, if these trips are made with someone else it is better because accommodation and transportation are shared in expenses
