We stayed at Rodrigo's apartment for 7 days. The check in process was easy, Rodrigo met us at the apartment and explained everything.
Apartment is very cosy and had all what we need. Location is the best in Buenos Aires, easy walk to all major sites, nice restaurant across the street and not too much traffic and noise.
Communication with Rodrigo was easy and fast. He was always available to answer all our questions.
If you want nice lovely place to stay in the great location I will strongly recommend Rodrigo's apartment.
