It is a nice place to stay if you don't mind dealing with traffic and staying in a very busy area of Buenos Aires. We usually call that neighborhood "once". The apartment is particularly safe because is next to "Argentine Hebraic Society", therefore there are security 24/7 in the entire block (for those who know some Buenos Aires history, will understand why). I didn't meet Patricia, but she made everything very easy to us. Overall it was a nice place to stay :-)
