I spent 5 nights at Micaela's Apartment in October 2022. The place had everything I wanted as a solo traveler. Quiet street and Micaela lives next door in case I needed anything. She was very welcoming and helped answer questions I had.
The apartment is very close to a metro Station. Very convenient. The neighborhood is up and coming but not as loud as Palermo or Recoleta. If you want to stay somewhere with a neighborhood vibe and less of a tourist vibe. I recommend Micaela's.
