I booked Angels airbnb for my brother when he came to stay in Buenos Aires and he absolutely loved the place. Not only is the location great (close to many sights, Western Union right across the building, and easy to reach public transportation/ taxis), but the flat also has everything you need and was super well equipped and tidy. We extended the stay twice and Angel was always super helpful and let us change the reservation with the utmost flexibility. Would definitely recommend.
