We had a great stay in Palermo! The neighborhood was our favorite in all of Buenos Aires: tons of coffee shops, grocery stores, boutiques, restaurants, and bars. The street is quiet and lined with beautiful trees, and you'll also find some lovely parks nearby.
The apartment looks just as pictured -- we especially loved the plants and natural light. We stayed for a month while working remotely, and it had everything you might need (extra towels and sheets, even a salad spinner!). The shower had good pressure and got really hot. Yanina was friendly and quick to respond to any issues.
The only issue was with the wifi, which was spotty and slow. We made it work, but if you need to do heavy internet work (video calls, downloading and uploading), it might not be the best choice. That said, there are several cafes and coworking spaces nearby with fast speeds.
