Had a good stay at Natalia's place in Recoleta. Natalia was very helpful, and accommodated us even when our flight was delayed by 14 hours. The apartment is small and cozy, and I would recommend more for 2 guests than for three. The one thing to note is that the apartment is right by the elevator, which turned out to be fairly noisy, so I would keep that in mind. Overall a good place to stay close to many great attractions in Buenos Aires.
