You can take hot shower with solar energy in the evening, and regular calefaction in morning.
La Serena, Chile
close to the bus terminal, close to the main square (both about 10 minutes walking), nice and helpful staff, absence of lockers, breakfast not always on time (it should have been served between 8-10 but even at 8:45 nothing was on the table) - so it could be a problem for someone who would like to eat it early, possibility to wash your clothes and enough space for it, no limits of hot water (like the control in some hostels that hot shower should be 5 minutes or less)
