Nailed it: perfect location, very bright, great views of Recoleta Cemetary, balcony with 2 chairs, lots of windows, fully equipped apartment, Free Netflix, wifi works great, 2 elevators, sun all day, there is a safe for valuables, building has double gate, doorman, lots of books and guidebooks, power bars to take Canadian and US plugs (no adapters needed), landline for local calls to book restaurants/taxis etc. Owner and host very helpful and responsive to questions.
Areas for improvement: install washing machine, a couple of small tea tray tables for eating on (there’s no dining table), provide garbage bags, create a "welcome booklet" with info on how the stove works (it’s tricky), how to get the outer window shutters up and down, how to get Murphy bed down, recommended restaurants, safest taxi companies, closest subway stop, location of large supermarket, etc. Make sure to ask these questions to the check-in host. The traffic noise from bedroom can be a bit loud at night, even though apartment is on 9th floor, just late night hustle and bustle of the city. (Windows are thin glass and can hear lots going on outside). Double paned glass might help.
These things are just “nice to haves” based on other apartments we have rented during our travels. They by no means take away from the greatness of the apartment and the wonderful experience we had in BA. You can't go wrong staying here! Beautiful spot!
