I would definitely recommend the Alan's apartment - perfectly located in one of the best neighborhoods in Buenos Aires, bright, comfortable, clean, well furnished, equipped with all you need for a short or a long stay. Alan is also a great host - very responsive, reacting fast on every need. We stayed in the apartment for 2 weeks and enjoyed the great area full of resaturants, bars, shops. It was really a great experience, being for the first time in BA and the Alan's apartment was the perfect choice.
