Mario is super attentive and always available to accomodate. He makes communication flow smoothly! Pros: The apartment is beautiful, super luminoso (lots of streaming daylight), and has been renovated well, with good taste and comfort in mind. Modern and tasteful. Pleasant views of the city in a part of town where there are still low-rise buildings. Located right next to an official bici-senda (urban bike path) if biking around is your thing. Just so you know, there are three bedrooms in the place. The master bedroom is usually kept for Mario's private use when he is in town but the other two bedrooms available for guests are nice and accommodating. The bathroom available to airbnb guests is admittedly small, with a small window, consisting of a shower stall and toilet but again outfitted with style and for comfort -- there is a metal apparatus on the toilet that I imagine provides the services of a bidet (Mario, correct me?). I feel Mario clearly did his best with the apartment space available in terms of renovation. He also took the time to prepare a guide pdf to the city and provides ample maps and info to out-of-towners. His mom, Norma, is super accommodating and friendly, but does not speak much English, just so you know, but the guide does compensate for this. FYI: there is no elevator in the building but three short flights of stairs that aren't a big deal if you're ok health-wise. The neighborhood is just a few blocks away from Palermo Hollywood and the Palermo district... which is where the posh, fun, hip, cool bars and restos are, but located in an unpretentious part of town that touches the nerve of a real authentic barrio (neighborhood ) of Buenos Aires if a grittier, down to earth authenticity is what you're looking for. Best of two worlds if you dare to venture out and explore a more honest side of the city (Villa Crespo, Almagro) which you can mix up with the chic and "cheto= posh" (Palermo). Caveats: while in a great location relative to the hip sectors of the city, the tango districts, and the red B Line subway that takes you downtown and buses/colectivos, it's unfortunately located about a block and a half away from a railroad crossing. This means the railway bell alarm will go off every so often -- it might bother you or not, it's not loud or blaring, but definitely noticeable and if you're of a quiet, sensitive persuasion it might bother you. There is also occasional traffic on the street but how you will react to it depends on where you come from. Two of my roommates, from quieter places in Canada and Portugal, thought it somewhat noisy but for me, a woman who's lived in Bs As for years, I didn't notice it that much at all. BA is typically a pretty noisy city so be warned, that's just the way it is here. As for safety, though the apartment...
