I stayed in Jose's place for an extended period of time and also worked from the apartment, so I can truly say that it has all the amenities that you could possibly need for either a short or long-term stay, as well as a Wi-Fi connection that is fast enough that you can work from it. The apartment is in a great central location and you can easily walk to attractions in central Santiago, Bella Vista, Lastarria, and more. It's also very close to the metro, supermarkets, and restaurants.
Jose was also an excellent host and very responsive whenever I had questions. My entire stay was perfect and I could not have asked for a better location or host!
