Renting a house at 2700 meters sounds quite nice. I've spent a night camping at 2200 meters before, and it was quite enjoyable. High pressure reduces the amount of oxygen in the air. This could be detrimental to someone unaccustomed to it.

My campsite was away from city lights, so the sky was magnificent.

Your campsite looks great. Weren't there any wild animals like bears? Bears will come near the area if they smell food.
