I've been living out of Airbnb's for two years now (traveling the world), and this studio in Palermo was one of my favorites!
The apartment itself is clean and bright (with lots of natural light), and the balcony is great to eat, work, or relax on. It's located in a beautiful, safe neighborhood just blocks from a gorgeous park with a big lake in the middle (Lago de Regatas).
This part of Palermo quiet at night (so you can sleep), but it's a short walk to Palermo SOHO and Palermo Hollywood (with cafes, restaurants, and night life). And if you want to get to either of those places quickly? There are always tons of Ubers in the area. Or you could do what I do and rent a Grin Scooter (one of those electric razers scooters) with your phone—there's always some within a block or two, and there are bike paths that North-East/South-West leading to those two barrios.
Finally, Flora is an amazing host. She's always there when you need her. She recommended good restaurants, a great housekeeper (since I was doing a long stay), and a place to change money at a good rate.
The bottom line? Book this apartment right away if it's available! You'll love it.
