This is a review for a party of two. Marta is a terrific host. The apartment is not just as shown in the pictures, it is BETTER. If you are used to being pampered a bit when you travel, this apartment is the right fit. All the amenities are great and the apartment is decorated in style. The location is probably one of the best in terms of access to grocery stores, public transport (subway, buses), museums, shopping malls, and restaurants. For those of us who enjoy a vegan or vegetarian diet, this neighborhood is quite a treat. There's two local whole foods stores, one just down the street on Peña. There's plenty of other options for dinning and delivery. The building is safe with a 24/7 doorman (what else can you ask?). I was concerned about Buenos Aires during the winter and being on a top floor with a wall to wall window. No need to be concerned. We didn't have to use the heating system. The apartment, because of how much sunlight it gets, stays at a perfect temperature throughout.
One of us travels with a walker (for mobility-related issues) and the building and the apartment are, to a great extent, accessibility-friendly. The built-in closet is spacious (we fit three large suitcases in it, all our clothing for a two-month trip in Argentina).
We were lucky to meet Marta and Federico in person. They helped us figure out last minute errands when we were leaving. They are personable, kind, and thoughtful hosts. Before, during, and after our visit, all communications were clear and easy to follow.
We'd be lucky to come back and stay at Marta's again. We'd recommend this place to anyone.
