We just finished a 2-week stay in Los Lagos Nr 40, which is directly next to 39 and part of the same group of houses (identical setup inside).
The house itself is very nice, but we were very disappointed that the large shared pool (key reason for our booking) was empty and "in repair" during our whole stay. We did not really see any progress during that time. There was a small shared pool left fo us to us, but only 1/3 or 1/4 the size of the one that was advertised.
The 3 bedrooms each have a seperate bathroom with shower, but unfortunately the 2 on the first floor take a very long time (5-10 min) to produce hot water - and even when they do, the pressure is very low. So we ended up cueing for the shower in the basement.
