Be prepared that a vacation in Marbella will cost a lot of money - the resort is promoted and popular. First of all, visas and round-trip air tickets will cost on average 500-700 EUR (for two people).
The next significant item of expenses is accommodation. The upper limit here is very high (for example, a double room in a 5-star hotel can cost up to 600 EUR per night), orient yourself at least 30-40 EUR per night. Judging by reviews, many people spend their vacations in Marbella in rented apartments - so, a week's stay in an apartment or villa with 3-4 bedrooms will cost from 500 to 1500 EUR.
The third component of the price of vacation in Marbella - food. On average for lunch for two in an inexpensive restaurant will cost 10-25 EUR (as in all of Spain, the portions here are large, so that girls can quite eat half a portion), a snack in a cafe will cost somewhere in 10 EUR. If you are going to travel from Marbella to Cordoba or Seville, count on 150-200 EUR per group (about 30-50 EUR per person).
On average, for a vacation for two people in Marbella we advise you to set aside at least 1500-1800 EUR.
