I enjoyed my few weeks near Retiro Park. The apartment was as expected, with a well-equipped kitchen and a few staples which made it easy to eat at home without having to buy everything. Elizabeth met me at check-in, which is a nice touch these days., and communication with her was amazing (seriously, one of the best hosts I've worked with). The apartment was, indeed, quiet, and with the fast Wi-Fi, I was able to work there like I would have back home.
There were plenty of great dining options in the area, and most of them had outdoor seating, a plus these days. I even found gluten-free bakeries within a quick walk; I probably had Holy Grain cinnamon rolls for breakfast a couple of times too many. Having that great park next door was a real draw for me, and I spent a part of most days exercising there or just enjoying being out in the peaceful space for a while. You're close to the Prado and the downtown high streets, but secluded enough to find your own space, too.
Overall, a great Airbnb experience.
