It would be hard to overstate how helpful Jim was in preparing us for our stay in Buenos Aires. Not only did he write explicit and responsive emails that accurately depicted the apartment and neighborhood, but he also provided excellent restaurant and tourist recommendations, solid transportation advice, and a vivid sense of the life of the city. Friendly, knowledgeable, and available, he made sure we settled in comfortably and departed safely. His user's guide to the apartment, sent in advance, was most helpful.
The apartment is basic and entirely serviceable, with storage space aplenty and fail-safe WiFi. It is indeed in a prime Palermo location, but after our two-week stay it would be hard to tell what's not a great neighborhood in Palermo. At no time did we feel unsafe. Easy walks to markets, cafes, and shops are in all directions, and the Subte is just a few blocks away. Taxis abound.
Know this about Palermo: It's noisy, gritty, pulsing, and fun for all ages. Get out of the apartment and explore! Would I return? You bet.
