I enjoyed my stay at Rosario's place - I ended up extending my stay an extra month! Check-in was friendly and accommodating. The space is modern, clean, spacious, the bed is comfortable, and the location is prime. The absolute best part of this place is the incredible view - the sunsets are amazing! There were a few hiccups in the beginning, but any inconveniences were met with a quick response and attention. Also, note that there is quite a bit of street noise, but that is part of the charm of Buenos Aires! I definitely recommend Rosario's place, she is an excellent host.
