Mariano's place is wonderful. It is beautiful, stylish and incredibly clean. The kitchen has everything you need to cook meals, though all I did was heat up leftovers. I could easily control the temperature of the apartment. When I was there, it was warm some days, and the air conditioner functioned well. The place even has a washing machine, which was awesome. In addition, Mariano is so sweet, helpful and responsive. He really is wonderful. Just note, the apartment is between San Telmo and La Boca. I felt extremely safe in the area, although many people warned me that La Boca is a dangerous area (mainly at night). For reference, it takes approx 50 min to 1 hour via bus to get to Palermo (a popular area). There really isn't a subway station close by.
