We spent a wonderful five weeks in this elegant, spacious, luminous, and surprisingly quiet apartment in a well-maintained older building, located on a side street off bustling Avenida Santa Fe. The apartment kitchen was well-equipped. Every necessity—grocery stores, pharmacies, subways, buses, banks—and amenities—restaurants, bakeries, pasta stores, fruit markets, bookstores, newspaper kiosks, and clothing stores—were available within twenty feet or a couple of blocks. Our host, Marcela, was charming, knowledgeable and very responsive, greeting us when we arrived and also saying good-bye when we left (a first in our Air BnB experience). She provided us with suggestions about art museums, restaurants, and arranged promptly for repairs whenever needed. She also just checked in periodically to make sure things were going smoothly. The superintendent of the building was equally responsive. (We do speak Spanish, which may have aided some of our interactions.) We strongly recommend this apartment for long as well as short-term stays.
