We stayed here 1 night after taking the 3 day Salt Flat tour from Uyuni, as we had a flight from Calama to Santiago the following morning.
Check-in was great, the room was excellent, and the beef burger and chips which was delivered by room service was truly amazing! (This may have been due to the unfortunate 72 hour experience which preceded my check-in here, but I digress!)
The hotel is large but was almost empty, I guess - owing to the winter season at the time. Fine by me, as I had an excellent night's sleep.
Taxi to the airport cost $10 USD.
