We had booked a different place to stay, but when we arrived, the rooms had no AC and the place was too far from the town center. So, at last minute we searched for hotels with AC close to the center, we found only a few options and Copasu was the one we chose.
First of all, the staff was SO friendly. They treated us really well (including surprising us for our birthday with a slice of cake and candle). They have comfortable rooms, with TV, AC (a must in Madre de Dios), great WiFI, room service, a nice breakfast buffet, and pickup from the airport.
The only bad thing about the hotel is that it had no elevator (I don't think there are many buildings in the area and most don't have elevators), but they told us that in a few months they would be adding an elevator, pool, and more rooms. So, soon this hotel will be even better.
Once again, we had a wonderful stay and we were very very grateful to the staff that made our stay very pleasant.
