I stayed for over a month at the apartment. Sebastian and his sweet mother Evelyn were responsive and helpful. The terrace is fantastic and I loved the sunsets every night. This is the 6th apartment I've rented over the years in BA and like many others, it's not silent. The glass is beautiful but far from soundproof, but again, this is common in a big, busy city with lots of nightlife. I recommend bringing a fan or white noise machine. Internet was fast (was using a VOIP phone for work with no issues). Sebastian deserves extra hosting points for being my hero when my Uber ride didn't work out and on the spot changed my US dollars for the extra pesos I needed for the taxi and stayed with me and helped me hail a taxi. Lovely guy. Mil gracias Sebastian!
