I had a very nice stay at the house of Ibras family.
The room is small (as seen in the pictures) but has a comfortable bed and is connected to a nice terrace where you can hang out.
Everything was clean.
Ibras Mom Sol made nice breakfast for me and we had some good conversations.
The place is located about 30 minutes walking form the center.
I recommend to stay in this place if you are in Santiago for 1 to 3 days.
