We stayed in Javier's apartment for 8-9 days in Jan 2019. Simply put, it's an incredible place. Over the last 4 years, I have spent 9 months renting different AirBnBs in Buenos Aires. This is absolutely the best I've every stayed in. For starters, Javier's co-host, Guille, is amazing. If there's an issue, a question, a need.......Guille is on it urgently. I've legitimately never encountered a co-host who was as hard of a work, honest & reliable as him. He really makes the stay that much more enjoyable.
Javier's apartment is located on a famous plaza. It's a beautiful spot to be. And, if you have kids, there is a nice little tree-shaded playground on the plaza for them. The apartment is a short walk to Palermo Soho (~.50 mi). It takes all of 10 minutes to walk to the best area in the city for restaurants & shopping. The benefit of the location though, is Javier's apartment is in a residential area. So, you don't get all of the noise you'd get right in the heart of the action, but you're only a handful of blocks from the action. There's also a subway line less than 2 blocks away & tons of bus stops right out the front door. For visitors to Buenos Aires, it is totally safe riding the subway, train & buses here.
Inside, the apartment is as nice as anything I've ever seen in Argentina. It has central A/C (which is unheard of). The shower is like bathing under a spa-like fire hydrant. It's amazing. There's a huge Jacuzzi tub in the master bedroom. Every last detail of the home has been remodeled to a 4 or 5-star level. I don't see how anyone could be anything but impressed. It's nicer than my home, and I live in one of the richest neighborhoods in Austin, TX. The balcony is also huge and a nice place to sit outside and unwind and enjoy the breeze.
I will absolutely, absolutely be back! We're already talking about renting his apartment for 3 months next year.
