Excellent Airbnb, and a great walkable neighborhood in Palermo with tons of restaurants and cafés nearby. Gonzalo, the property manager, was extremely responsive and allowed us early check-in based on when our flight arrived in Buenos Aires, which we really appreciated. The 24/7 security staff made checkin and checkout super easy.
The wall-mounted AC unit kept the apartment sufficiently cool, and the community pool was awesome to use in the summer heat. Wifi was good. The building’s communal washer machine worked fine, but keep in mind only one resident in the building can use it at a time in 3 hour time slots, so definitely plan ahead for this.
Two small recommendations: would suggest supplying guests with soap, shampoo and conditioner (was annoying to have to bring it from the US/buy it from a local shop), and I would also recommend having extra towels available to use after using the pool.
