I really enjoyed by 5 day stay here. I've stayed in many Aribnb's in Santiago and they have always been modern apartments in high rises. They have been nice, but kind of sterile. Alvaro's apartment is a nice, large older apartment with real character and very good (I think) art. Location is great - 5 minute walk to the metro, not far from Lassataria which is hopping, nice view on the park. All that being said, it is kind of an old apartment and if your expecting a gleaming bathroom with new fixtures, you'll be disappointed. Same for the kitchen - it all works and everything is clean, but a bit old fashioned. That's the only reason I gave 4 instead of 5 stars.
Having said that, I really enjoyed it and it's a great value - large spaces, high ceilings, nice view. Highly recommended.
