Héctor has an excellent location here.
The apartment is beautiful and in a safe and very walkable area. It was a great fit for us, since we needed secure parking and it was available. The apartment has high-end furnishings and solar screens and fans kept the apartment comfortable even during February summer for our small family.
Shower and tub worked great and kitchen worked well for what little cooking we did.
In the ground floor of the building are a Subway and an Oxxo, so basic food items are easy. Walking about 1.5k can take you to a really nice mall, a taxi will take you for less than $5 if you don't like to (or can't) walk.
Thank you Héctor, we would definitely check first with you for availability if we return to Santiago!
