Formerly called Hostel Africa, this is still known by that name by those who live in Marbella. Nowadays it belongs to the Andalucian government, and its facilities have been modernised. Here you'll find comfortable, cheap accommodation in the heart of the city of Marbella. The building resembles an old Andalucian farmhouse, with a garden and sunny terraces for relaxing or sunbathing. The beach is about fifteen minutes walk away, through the entire centre of Marbella, or you can take a bus.
The hostel has a swimming pool, tennis court and parking (something to consider given the difficulty of parking for the downtown area). Prices range from 12 Euros to 25 for those under 26 years, and 18 to 30 for those older (includes breakfast). Remember, you have to have the Youth Hostel Card, or get it on arrival and that will entitle you to enjoy very good priced accommodation with activities (if desired) all over Andalucia.
