This apartment is really the cutest, most cozy place imaginable. It is exactly as it's pictured and is in a great area close to a wonderful park and lots of restaurants are in walking distance. The neighborhood is very serene and safe. The property is owned by Daniela and Diego who live downstairs, and I communicated solely with Daniela. Daniela was always available and responded fairly quickly to texts. She was very patient with me when I first arrived as I was traveling alone and in Chile for the first time, so I had a looooot of questions; all of which she graciously answered.
The only real issue I had was the internet, which I don't believe was in their control. As a reference, I'm now in Colombia and having the same issues with the airbnb provided wifi. I stayed in Chile for a month and I work from home, so good internet connectivity is a must. I ended up buying a travelwifi device for the gaps in coverage which was sometimes spotty all day, and it saved me (and I'm sure Daniela) a lot of stress.
Overall, very sweet couple with a beautiful place which I 100% recommend!
