I would recommend the apartment. Martino is a super host. Martino's response time to inquiries were immediate and there was always a positive interaction and result.
My stay was for five weeks, and I would have been comfortable staying longer. A nice, newer apartment located in a quiet neighborhood with natural sunlight. The apartment has everything needed for a pleasant stay. It was a short walk to groceries, veggies and fruits, ice cream, restaurants, laundry and buses. Across the main street, after a walk through a neighborhood is the train station and a nice area of restaurants and a plaza.
If you're wanting to be in CABA but in a quieter area, this is a good choice. One can take the train, and buses to any area that you want to visit. Martino's apartment is a comfortable place to stay.
