Absolutely horrendous service.
Initially we found the guy at reception to be helpful and friendly. He was happy to store our bags (as we arrived hours before check-in), and his English was great.
However, after check-in things just went downhill. We had booked a twin room (as we did not feel comfortable sharing a bed), but only after entering the room did we see that we had a double bed. We went down to reception to try and resolve the issue, but the guy was very rude and just told us we had paid for the room now, so it wasn't his problem. We tried to explain that we paid on the premise that we thought we had a twin room, not a double.
Eventually we asked if we could get a spare mattress, so one of us could sleep on the floor, but they wanted to charge us for it. Even though they screwed up our booking and put us in the wrong room. Eventually we managed to get them to give us an extra blanket and pillow, but it still meant that someone had the cold, hard floor to sleep on.
Lighting is also terrible, and the WiFi has terrible connection throughout the hotel.
Rather stay a few km down the road and make your way into the GeoPark by car/taxi if that's what you're here for.
