The fire, that started around 1am, was located some 300 metres from the centre of Puriscal, a thriving community in the mountains west of Cuidad Colon.
The director de Bomberos (Fire Department) Héctor Chávez said fire crews were on scene within 3 minutes of the call, but couldn’t do much for the 60 year old building.
Most were able to get out, suffering smoke inhalation and bruises, but five did not.
Chávez said they suspect an electrical problem caused the fire. An investigation is underway.
