Juan's place is centrally located and in a safe neighborhood. There's a major supermarket within a very short walking distance. There's also an abundance of excellent restaurants within a 5 minute walk. Communication with Juan and his team was rapid and excellent. If and when I return to Santiago, I would certainly stay there again.
One thing to note is that there's an open stairway that leads to the bedroom and bathroom. Some elderly people and anyone who might have difficulty walking might find this to be an issue.
