My sister and I stayed at Gustavo’s apartment during a holiday in Buenos Aires. It was much better than I expected! The place looks even better in person ;) Location is perfect, very close to touristic places such as Palermo Soho and Recoleta. Everything was very clean. I asked him for flexibility during check in/check out time and we could arrange that; communication with him was very fast; he has a really good recommendation for Tango shows - the van picks you up at the apartment and than drives you back. Also, Gustavo booked a transfer for us and the service was really good!
I definitely recommend! Thanks for the hospitality, Gus. ;)
