You can reach Tasty Dayz Hostel is either to book a shuttle from the SJO airport (around 50-60$) or take the Mepe bus from the Terminal Atlantico del Norte. You'll have to get a cab ride (40$) to the terminal but then the bus is about 10$ directly to Puerto Viejo. From there, we can organise you a cab if we know in advance or you can grab one for 2000 colones at the bus station.
