Astro's place is very well located for a budget stay in walking distance of tourism and restaurants. We stayed with our teenage kids and enjoyed the freedom we had to leave the building, walk a short distance to food, entertainment, restaurants. We walked at night as well and felt safe. The buses and subway are right there. Taxis are plentiful.
There are a few delayed maintenance issues with the apartment but for us the location outweighed those issues. The beds, bathroom and kitchen are fully functional. Enjoyed the water filtration unit in the kitchen. The front lobby clerks are friendly and helpful. Luis, Atro's local advocate was super responsive and has connections with Teatre Colon. We enjoyed understanding a bit about the state of music in Argentina.
