I had one of my best Airbnb experiences in this apartment. We spent three weeks in Jonathan's place during our holidays visit to the family in December. Me and my wife have been living abroad for the last 4 years but we were both born and raised in Buenos Aires, so we already knew that the location was extremely convenient to reach all the interesting places of the city. You get all the perks of trendy Palermo without all the night time hustle-and-bustle.
Building is quite new, comfortable and very safe. The apartment is sparkling clean, well equipped and very nicely decorated. The amenities are accesible to the guests and they definitely add a plus to the stay, specially the pool in hot days and the gym to burn all the 'asado' ;).
Finally, the host and co-host were super responsive and even proactive, they made us feel at home at all times.
Five stars, world class stay. Totally recommended.
