I stayed five days in Natalí apartment, which was conveniently located close to the location of the conference that I attended in Buenos Aires. I was greeted by Natalí's brother(?), who during check out was nice enough to call and order a taxi to the airport. I did not meet Natalí in person, but she readily replied to all my e-mails. The apartment was clean and well equipped to my needs. It is located in a commercial area downtown, which means that its immediately surroundings are rather deserted at night. It's a very affordable and handy accommodation.
