We stayed in the apartment for one week. The location is great! One of the bedrooms and bathroom is very spacious and comfortable. The second bedroom and bathroom are not. The bunk beds in the second bedroom are uncomfortable and the small bathroom is much too small.
Eugenio, the host, is very nice. He left a fruit platter to welcome us he also left us a metro card and a phone. We went over Easter, so left a basket with chocolates. Although we didn't meet him personally, we felt like he thought of us enough to give us lots of very practical information about getting around in Santiago and surrounding area. The kitchen and washing facilities, were good.
I would recommend this apartment to a couple, but not to a family.
