The apartment was beautiful and in the center of a great neighborhood. It was within walking distance to many fine restaurants, shops, and sights.
The check in process was a little rough for us but that was mainly due to our lack of Spanish and getting from the place where you pick up the keys to the apartment. It is not far but with luggage you need to get a taxi or car but without cell service or Argentine pesos it can be difficult. Also, if you are a foreign visitor remember that the ground floor is not the first floor.
