Overall decent venue, located in the quiet area between the towns of Soldeu and Tarter. Towns are not big so if you have a car the location is absolutely fine and just ~5 minutes drive from both ski stations.
My biggest complaint with this property was the noise from the heating system/circuit breaker. Our first night was terrible as we heard a loud "clicking" noise from the circuit breaker every 5 minutes, and a blue light from the heater would flash in the bedroom at the same time. It was the temperature control turning on/off the heating system, not sure why it's connected to the circuit breaker but they are linked. Needless to say it was a sleepless night. The women at reception were able to fix the problem the next morning and were nice, but I was super frustrated by this experience and each time we heard the noise subsequently (which continued but much less frequently), I was concerned we would have another bad night (even though we didn't).
Other than that, the apartment is small but fine for 4 people (2 adults, 2 kids). Beds were not very comfortable but fine. Sofa was incredibly hard (I was uncomfortable after watching TV for 1 hour); we did not try the sofa bed.
I appreciated the starter kit for the kitchen (sponge, dish soap and towel) and the laundry (1 package). Kitchen has basic amenities (pots, dishes, toaster, coffee, kettle) and allowed us to have breakfast and a few dinners at the apartment - a welcome feature when traveling with 2 young kids.
