We staid at Patricio with a colleague while visiting Santiago for a conference. Patricio and his wife have been very responsive, flexible and helpful throughout. I think that the flat is better than it looks in the pictures (and feels larger). A big plus for me is that the apartment is overall quiet, despite being in the middle of a busy area, very well connected to transport (subway at 5 minutes): the building is in small residential street, and the flat is top floor. The apartment is very light, felt very warm despite staying during a rather coldish week in spring (i assume in winter it is warm). The beds are comfortable. We have not used the kitchen much, but it is equipped for cooking. In sum, we had very good stay and could sleep, work and travel around the city very well.
