Agustín is a fantastic host - really easy to get hold of before and during the trip and full of tips on local restaurants, sights to see and any other questions we had! The apartment itself is bright and clean, exactly like the photos. The location is great, close to the subway and near lots of bars and restaurants (though can get a bit noisy at weekends, something for light sleepers to bear in mind!). There's also a little balcony for breakfast or a pre-dinner drink! I really recommend Augustín's apartment as a base for exploring Buenos Aires - we had a really great time.
