Olimpia Hostel in Atacames, and is located right in the middle of Transportes Esmeraldas y Transportes Occidental, the main transport companies which travel to Atacames. So, once you arrive in any transport company you will have to walk 50 meters to get to the place. It is at the 3rd floor of the 'Centro Comercial Olimpia' building. Just ask for "el Olimpia", everyone knows it ;)
