I would definitely recommend staying at Constanza's house. The communication was great throughout, there was a slight hiccup with the keys on the first day and they handled it very quickly and followed up to make sure everything was ok and were available via Whatsapp in case anything came up. The apartment was very comfortable, with amazing views of Las Condes and the mountains. A very large balcony and comfortable and cozy living room made us feel at home. The apartment is located off a main road, so for any folks that are sensitive to noises, some road traffic does come into the house if you have the sliding glass door open. The beds were very comfortable. The master bedroom is pretty spacious with a walk in closet with built in shelving, but the guest bedroom is pretty small, so if there are two people staying you may need to share the master bedroom closet to store clothes/luggage. It was about 20 minute taxi ride to Parque Metropolitano, centro, or Providencia.
