I booked five nights at the Palermo Viejo B&B, which didn't appear in any of my travel books, purely on the advice of TripAdvisor. Certainly, Ariel, the B&B's proprietor was very helpful and responsive over email, but I couldn't help but feel a little nervous about venturing out beyond the Lonely Planet, etc. Any anxiety I may have felt was quickly alleviated upon arrival. After getting out of our taxi from Ezeiza, we were warmly greeted (in English) at the door by Ivanna, who gave us a quick tour of the property and helped orient us to our surroundings with a map and ideas for activities in Buenos Aires.
The Palermo Viejo B&B is located right off the intersection of Scalabrini Ortiz and Niceto Vega, in the hip Palermo Viejo neighborhood. Scalabrini Ortiz is a very busy thoroughfare with lots of buses and taxis whizzing back and forth, but the B&B is tucked away on the small side street of Niceto Vega, which also takes you into the heart of this quaint neighborhood packed with hip restaurants and boutiques. All the cutting-edge Palermo restaurants you've heard or read about are well within walking distance of the B&B. The location could not be better for exploring Palermo. Connections to other parts of Buenos Aires are also easy from here. Taxis are plentiful and cheap. The closest Subte station is about a 10-15 minute walk. There are a couple banks with ATMs around the corner on Cordoba, and supermarkets and grocery stores a couple blocks away on Scalabrini Ortiz.
The rooms are well appointed and clean. Ariel converted his former family home into the B&B, giving the guest rooms modern touches such as stained concrete floors, Scandinavian-style furniture, air conditioning, cable TV, Wi-Fi, and private baths. There is a small but lovely garden courtyard facing the rooms, and the common living/dining room is an excellent place to chat with Ariel and Ivanna or other guests about travel suggestions. The common room has a small library of travel books and a computer for free Internet access. A standard continental breakfast (pastries, yogurt, coffee, tea, and juice) is served late into the morning, something travelers will appreciate once they adjust to the late night culture in Argentina.
Ariel and Ivanna are gracious hosts and more than willing to help guests with reservations for transportation, restaurants, tango shows, etc. This comes in handy if your Spanish language skills aren't so great. And from what I could gather, that was the case for many of the guests, who seemed to come primarily from the United States, Canada, and Europe.
The rates are very reasonable, given the quality of the rooms, the service, and the fantastic location.
