Maria's place is great and very comfortable, it was very easy to get in and out of the building and the building was top notch. Maria was very accommodating! The rooftop is amazing with a pool in which you can do short laps and is surrounded by many sunbathing chairs. There's a grill area too however that needs to be reserved in advance. We went to Casero's the first night and had a wonderful steak dinner. The apartment is near Defense which takes you past cool shops and old buildings, including the San Telmo market, to Plaza de Mayo (where Casa Rosado is located). From there we took the Subte to all the various neighborhoods. Doppleganger, a few blocks north of the apartment, is a great place to get cocktails. Bolívar opens up at night and there are a ton of bars and restaurants that dot the street. We ventured off onto Ave. Chile and walked into Garage Bar which was pretty cool. All in all this was a great location though some of the streets may seem a little transitional - you can always grab a quick cab or jump on a bus.
