We were in town visiting our daughter who is studying for the year in Santiago. The apartment was only two blocks from her place, which made it very convenient for us. But it is a great location for anyone, very convenient to 2 metro lines, buses, and walkable to many of the places a visitor will want to go. You can walk to Lastarria, Bella Vista, Plaza de Armas, etc., within 20 minutes.
The neighborhood is just adjacent to Providencia, and is very safe.
The apartment is very compact, but worked well for us. There is a small balcony with a great view of the Andes. The kitchen is small, but had everything we needed. Romina kindly left us a bottle of wine to enjoy. The building is very secure, with a 24-hour front desk, like most buildings in Santiago. Entrance to the apartment is very convenient with a smart lock.
Romina and her husband met us to let us into the apartment and show us all the details. They were very friendly and we enjoyed getting to meet them. We would highly recommend the apartment.
