Sergio's apartment is *amazing*. It is very clean, modern, comfortable, and has these breathtaking city views that can be seen from both terraces (or where the pool is as well). Sergio was very patient with me during my 1st time booking through AirBnB and even while I wasn't sure if it would be one or two guests. He also accommodated a very early morning check-out (3:30 a.m.) and Mariano, who also helped with check-in, helped to arrange a reliable taxi. Sergio's apartment has a nice binder with all the information in it a visitor could need or want which was excellent. It is close to many restaurants, bars, and cafes. It also happened to be about a 10 minute walk to where I was taking Tango lessons with Tango Piola which was wonderful and convenient. I hope that when I come back to Buenos Aires I can stay in this beautiful apartment again!
