We had a great stay in Emilios apartment. It was just as it appeared in the photos, right in San Telmo and just 2 blocks from the subway.
We didn't meet Emilio himself but a lady who lives upstairs works as a manager for him and was wonderful to deal with. We had no problems finding the place or meeting to get the keys. When we arrived she gave us a great introduction and info on what to see and do in the city and answered all our questions.
A perfect spot for a couple staying in Buenos Aires, we would have loved to stay longer.
