Ernesto was super welcoming. We arrived way later than expected, and he waited for us, and took his time to explain us everything, including a map of the city, where to go, how to go. He was always available for us, and very nice to us =)
The main negative point is the heaters that don't work out. There is only the air-conditioning, that is not enough to warm up the entire room, and no heater in the bathroom.
