What a great place! Located in a neighborhood close to the centre and with a bus station in front of the building, it is easy to fully explore the city (also thanks to the public transportation card available for guests). The studio itself is clean and the hosts are the absolute best! They give great tips (we loved the restaurants and bars at nearby Av. Caseros!) and are always available for questions. We had a problem with a cancelled domestic flight and Catalina was so helpful.
Oh, and the rooftop pool is absolutely amazing. What a way to start or end a day of exploring BA!
We definitely recommend staying with Andrea and Catalina.
