Cristian's place was beautifully appointed and impeccably clean. I cannot emphasize enough what a pristine oasis for my week stay this was compared to most airBnbs! It also had abundant hot water, awesome pressure, modern plumbing, and perfectly stable and fast wifi.
The secure building had kind concierges to buzz you in 24/7. While the building is on a street with hip sidewalk cafes and nightlife, the apartment itself faces quiet rooftops with a park in the distance, and the building and the posh neighborhood seem to be respectful of quiet hours from 11 pm onward or so. I slept great! It's also around the corner from some of the best eats in the city, and everything was either walkable or with easy transit.
100% satisfied and recommend for a perfect stay in Santiago.
