I loved staying with Mario in his fabulous apartment. The apartment itself is clean and modern and all of the amenities are new. There is a wonderful view from both sides of the apartment and with the windows open there was a great wind in the apartment which made it a great oasis to hang out in when the weather outside was too hot. The neighborhood is great- up and coming- filled with galleries and new restaurants are popping up around. It's easy access to busses and a 5 minute walk from a main subway line. Living with Mario himself was great- he's kind and I was able to have my own independent life but then also have some nice moments with him hanging around while drinking mate. He helped me find a Pilates studio in the neighborhood and gave recommendations when I asked. All in all a fabulous experience and I will probably stay with him again next time I'm in BA. Also - I moved to his apartment last minute as my last apartment was horrible and Mario was VERY flexible and helped me out a lot!
