Mariano's apartment is in a nicely restored old building with beautiful wood floors, lovely tall French doors opening into a pretty balcony overlooking the street, a nice living room, dining room and loft. It was a brilliant base for exploring San Telmo as well as Plaza de Mayo and a short bus ride away from La Boca. The neighborhood is a bit rough but it's safe during the day and we really enjoyed the vintage atmosphere of San Telmo. While I enjoyed the location and found the apartment spacious and beautiful, I would hesitate to stay here again. First of all It did not feel very clean, the kitchen sink and bathroom had unpleasant odors and there were tiny bugs and a small spider web under the sofa bed in the living room. The apartment, the furniture and other amenities definitely look more "worn" than in the pictures. Second there was no sound proofing in the upstairs loft and I was able to very clearly hear our neighbors' conversations for 2 days in a row. This was in addition to the street noise. Finally when we had any issues, such as with the wifi, the apartment was too hot or when we needed to make a phone call (no phone service in the apartment even though there was a phone), it was hard to find Zuni (Mariano was out of town during our stay).
