Casa del Cerro is an absolutely great place to stay in Santiago. The house itself is incredible and inspiring. As soon as we arrived we went to La Chascona, Pablo Neruda's house, just a few blocks away - and it gave us a feel for the incredible creativity and energy in the neighborhood. The sauna and the balcony make the house very relaxing and comfortable. We were out and about for most of the day but I could imagine spending the day relaxing around the house.
We were hosted by María for the booking and she was extremely accommodating, helping us pick a hike and a place to grab a drink at the end of the day. There are some shared spaces in the house but it always felt private and interactions were always friendly and accommodating.
It is important to say that the neighborhood is very loud at night.
