I stayed here for one week with my family for a conference. The area is safe and clean, with a wonderful park across the street that has a large playground for kids. There is a nice mall nearby with a supermarket about a five minutes walk away. Both the park and the mall has many restaurants that are family friendly. My conference was at the Best Western, which was a ten minute walk from the condo if you cut through the park.
As for the condo, it is in a newer building in a complex of new buildings. There is a guard in the lobby which made us feel safer. In addition, each floor has four large units, so it was very quiet. The condo itself was just like in the pictures- clean, modern, and with all the amenities.
Jessica was a great host. She welcomed us with a nice package of snacks and drinks. The condo also had toys for the kids. She also had great suggestions for activities and responded to my questions within a few minutes.
In short, this is a great choice for a very walkable area of Santiago. This was perfect for my family, and we look forward to staying here again!
