I am curious about the house though, given all our conversations here about home improvement loans. Can you please share with us your sensory perceptions of the home? Was it cold or hot? Were there strong odors? How do you think the house would be in weather, rain, snow, high winds?
Thanks for the questions, Kerry -- one of my plans had been to include a post with some photos about houses and businesses that reminded me of things we'd see listed on Kiva, so that's a perfect entree! To answer your questions about the home I posted photos of above, it was cool inside despite the warmth; I suspect the rock walls were effective for that. It smelled a bit musty and earthy to me, but the odors (say, from cooking or the guinea pigs) were not strong at all. There is no snow there, and very little rain, so this particular home in this particular area would not suffer from either problems. In fact, in some of the areas we visited, there is so little precipitation that there are many homes WITHOUT ROOFS at all: it only rains a maximum of 6 days a year, so they mostly don't need one to keep out the rain.
Some of the homes we saw had tin-sheet roofs (like Sofia's), some had thatch, some had bamboo with thatch over it (like this family's)... and a few had none. Here are a selection of house photos we took, including some of housing settlements. (Click the photos for larger versions.)

A housing settlement on the outskirts of Arequipa.

A home near Colca, with a partial new construction next door.

Thatch-roof home by a high lake near Colca, with stone pens for llamas behind. The residents are washing clothing in a small lake.

A house with a really small door (Charlie is really tall).


Sofia's home in Chivay (tin roof, earthen walls and floor).

The amazing home and ceramics workshop of Pablo Seminario, in Urubamba. (This is for contrast with some of the other homes.)

A street in Ollantaytambo just like the one on which the family home I visited was located.

The inside of the home we visited in Ollantaytambo.

Housing in the town of Aguas Calientes, at the foot of the mountain atop which perches the Machu Picchu sanctuary.

Very upscale housing on the hillside above Cuzco.
So that's a pretty wide set of housing photos, again, clicking on any of them should take you to a larger version of the picture. I'm happy to answer any questions, and I hope I didn't just blow out someone's dial-up line! MY APOLOGIES if I did!!
