We stayed here as part of a group trip, and returned back to the hotel on 3 separarte occasions over a 10 day period. We were in different rooms each time, which were always clean and tidy and a welcome relief after our camping and refugios. Whilst away the hotel retained our unwanted luggage, which was always in our new rooms upon our return. The staff were really friendly and accommodating and nothing was too much trouble. The availability of tea and coffee (free), at all times is another nice touch, and in reality the hotel became a little home-from-home for all of us.. Breakfasts were also excellent with scrambled eggs etc. and constant replenishment of all items.
Although the hotel is about 250 metres from the main part of San Pedro, this was actually quite a nice walk, and caused no problems. It also means that the hotel is quiet. It does have a pool, although it takes some finding, but you don't stay here for a swimming pool. Overall a nice, friendly and comfortable base for exploring the area.
Also San Pedro de Atatcama is a really nice town with good restaurants and bars.
