As always, Oscar was a wonderful host. He communicates promptly, and does everything within his reach to fix problems. Unfortunately, this time there were various problems that were beyond his control. Due to electrical outages in the building and the neighborhood, there were several days that the elevator and other things did not work, and we had to go up and down 8 flights of stairs. I still highly recommend Oscar as an excellent host, and the apartment is in a wonderful location, but Buenos Aires is going through a rough time. Our time there was exhausting.
