I spent a week at this apartment by myself and felt that I got a very authentic Buenos Aires experience which was exactly what I wanted.
The place is very comfortable overall. It is full of light as advertised and looks just like in the pictures. I loved doing morning yoga in the rays of sunlight downstairs (perfect hard floors for that!). Both beds are comfortable (I slept upstairs at night and used the downstairs bedroom for occasional midday naps) and street noise is minimal. The apartment feels very private, safe and quiet being in a pretty busy neighborhood of San Telmo.
The location is just wonderful, within walking distance of the main historical points in the city, public transportation spots and restaurants. If you end up walking to Plaza de Mayo, take Peru street and spot at Punta cafe for a cup of coffee. Hija de Tigre on Av Caseros & Bolivar has the freshest high quality nigiri, sashimi and sushi. Patagonia Danue on Av Caseros & Bolivar is great for ice cream.
The hosts (Sofia and her father) were the best part of this experience. They were so accommodating that it felt like I was staying with family. If I had any issues or requests, they were very responsive and provided the quickest possible solutions. I would recommend this place and come back to stay there again next time I am around. Thank you very much.
