I had a wonderful stay in Buenos Aires, greatly because of Martin's spot.
The Apartment :
The apartment has two bathrooms, a well stocked and clean kitchen, large living area, and comfortable Queen sized bed. But my favorite part of the whole apartment is the balcony outside. It was the same width of the whole apartment itself and it is awesome. Theres a grill where you enjoy cooking many asadas, a large table with enough room for 6 or so people, and has an amazing view! It's on a high floor so you get a good glimpse of Palermo Hollywood.
Another important thing for me is entertainment and reliable internet connection. It had a large tv, with some awesome speakers where you can hook up your phone, laptop, or whatever for some great sound. I work remotely for a living, so having reliable wifi was top priority for me. It was by far the most reliable internet I've had during my stay in Argentina.
Location:
Next, the location was top notch. It is situated directly in the middle of one of the most trendy neighborhoods (Palermo). You are in short distance of all the spots you wanna be. Wonderful restaurants, nice bars, shopping, supermarkets, and lots of entertainment. A short couple blocks away is also the Subte (Subway), so you are in close proximity to the rest of the city. The Palermo Park is also nearby if you need some breathing room outside of a city.
Communication:
Communication with Martin was fast and easy. If you have any sort of needs, he'd do his best to accommodate and to make my stay more comfortable. He also gave me some great recommendations for the area.
Overall, I had a 5 star experience and I hope to return to Buenos Aires soon.
