I stayed two months at Milagros' place and loved it! It was very peaceful which was perfect since I was working from home most of the time. Internet was super fast which was great not to have to worry about. It has powerful A/C as well which was nice during December since it was pretty hot. The neighborhood was beautiful and had plenty of restaurants and shops nearby. The rooftop also has a pretty cool view as well.
Milagros and Gaspar were super attentive to anything I needed. I would highly recommend this place to anyone visiting Buenos Aires, especial "digital nomads" and people like that!
