The location of this flat was excellent, with convenient metro stops and within easy walking distance of many key tourist areas. The close proximity of a grocery and marketplace made it possible to eat in and enjoy the sounds and rhythms of the city with the balcony doors open. Olivia provided written recommendations of restaurants and orientation to the neighborhood. I'd add that there are two wonderful Argentinean empanada places close, as well! While we didn't meet our hosts in person, Olivia checked in with us periodically online and made sure that arrival and departure were efficient.
