I was really happy with this apartment. The building is easy and safe to access, the apartment is well decorated and furnished, and the location is in a great neighborhood and well-suited to explore the city.
Alejandra is a top-notch host. She clearly has a good system and made check in/out very easy with clear and prompt communication. She also sent tips and info about the area daily, and offered to arrange tours and other activities.
The only downside worth mentioning is that the apartment is right across from a busy highway, so the traffic noise is pretty loud. This wasn't a big issue, but I was glad to have my earplugs for sleeping. Leaving the window open at night is not really an option since it's much louder when open. With the window closed and earplugs I slept well.
