Our stay in Buenos Aires was fantastic thanks to Oscar and his apartment! Oscar met us at his apartment upon our arrival and went over everything we needed to know along with several great restaurant suggestions near by. The apartment is very clean, full of all needed amentities, great size for 2 people & within walking distance to supermarkets, restobars, shopping & the recoleta cemetary. (It's about an 80 peso cab ride from Aeroparque fyi). The terrace is ideal on a sunny day - we had our coffee and breakfast out there each morning.
Oscar met us at 6 am for our departure and check out. AND he helped us hail a cab :-)
I definitely suggest Oscar as a host for anyone's trip to Buenos Aires!
