Guillermo's place was the first of Airbnb locations that I stayed in on an extended trip to Santiago. We were six in total (2 adults, 4 kids age 13 down to 5). For this number the apartment was compact, but is efficient and as such, we were quite comfortable. We did not meet Guillermo, but his mother and sister were waiting for us on arrival to the building which is located just across the street from a park with a playground. They were very kind and very helpful ensuring that we settled in and providing us some snacks upon arrival. This apartment is located on a lower floor, and while still at height is safe for smaller kids that are being supervised. There are plenty of shops nearby to this apartment, which is in a safe part of the center of Santiago and is close to the Santa Lucia metro station. I would highly recommend for adults, families or solo travelers. Great place.
