It's a very chic with old fashion yet modern furnished apartment, very close to San Telmo where the famous market and a lot of restaurants locate. Mauricio is very helpful by patiently replied all of our questions during the first meet and messages~ if you're looking for a down to earth BA experience, look no further~
PS, for convenience concern, just exchange the currency at the airport, the exchange house (cambio) and banks might not work with your time schedule (at least not in our situation, on weekends with pouring rain)
