Leo was a very helpful, accommodating host. Check in was straightforward and informative: he gave us lots of recommendations. He was also very responsive, quickly answering any questions I sent him.
The apartment is lovely, in a great location. Great bar and restaurant on the 2 corners next to the apartment with lots of other options close by. It is also really easy to catch one of the many buses to the city centre and other areas so the apartment is a great base to explore both Palermo and Buenos Aires.
