Griselda was very quick to reply to messages and arranged for her friend to pick us up from the airport ($40.00 USD) and drop us off at her apartment.
The cozy apartment is very clean and orderly.
Everything you would need - bus, subway, grocery store, shopping, café, bakery, and restaurants are all within 5-10 minute walk and the ferry terminal is about a 20 minute walk.
Many of Buenos Aires top sights are also within walking distance.
I would definitely recommend this location and Griselda is lovely!
