Dario's place was exactly as described. It's very close to the bus stop that can be taken for a short ride to the metro station. From there it is easy to get just about anywhere in the city.
Dario also gave us awesome suggestions for food nearby the apartment.
Dario's hospitality is bar none. The metro line was down one evening. Dario was our saving grace that night. He was able to guide us home via the bus numbers.
Highly recommended.
