We stayed a little over two months while working and sightseeing in BsAs and Alejandrina’s place was just what we needed. The studio is quite spacious, centrally located (walking distance to some of the city’s main attractions), and close to some excellent restaurants and cafes (La Motofeca, just down the street from the building, serves perhaps the best coffee in town). As a host, Alejandrina was always very attentive and quick to respond, and gave us some excellent tips on what to do for Christmas and New Years. She also included a cleaning lady that would come once a week, so the apartment was always sparkling clean — a huge bonus.
The only downside during our stay was that the wifi was a bit unreliable and slow, so I would perhaps suggest switching to a different provider. Recommended for anyone who wants to stay in the middle of the action in beautiful Buenos Aires.
