This time of year is not the ideal period for it, but apart from that, I wouldn't mind being back in the Cordillera Blanca myself!
The red tent is indeed a Hilleberg. It belonged to our neighbours at high camp, a party of Scandinavian climbers.
As it happened, my own tent was a Hilleberg too - a Nallo 3 to be precise. I bought it last year, specifically for the Cordillera Blanca. For two people, it's quite roomy, and it's not much heavier than the Nallo 2. Of course, three people would fit too, but I haven't tried that.
