We really enjoyed our first visit to Buenos Aires, enhanced by our comfortable accommodation - a retro-style loft with all the amenities for self-catering, & the washing machine was a real bonus (especially as we had just come from a round trip of Brazil!). Carlos' apartment is located in a central part of Buenos Aires, thus well-placed to see all the other districts - and easily walkable. However, taxis are very reasonably priced for further explorations or night time excursions. We loved BA and already planning a return visit!
