Sofia's apartment is excellent. The location is very convenient to the entirety of the Recoleta bario. There are plenty of places to eat and markets to buy groceries. It's is also only a few blocks away from a Subte stop that links to the rest of the city.
Sofia is an excellent host. She is timely and knowledgeable in her reponses. If you need immediate help, the building has a great portero who is available throughout the week.
I highly recommend this apartment in this location.
