I totally recommend the flat. Caro is also a great host, very easy to communicate. Location of apartment in very nice neighborhood, only 5-10 minutes to vivid nightlife of Buenos Aires. We just walked to these attractions at night and come back by walk again. Also around home there are several nice restaurants, Las Cabras, Osaka eg. We didn't use public transportation, Uber is very cheap and easy to reach in the city. All basic amenities are covered at the flat. Flat is also better than pics!
