I have stayed in several places in Buenos Aires and Martin and Anabel's studio is by far the best of those experiences. I stayed here 3 months. The studio is modern, clean, and has everything you need for your stay, including a kitchen, large shower, heater, and large refrigerator. The studio has a large bed, wooden table and sofa, a lot of natural light and trees and greenery on either side, making it a peaceful place to stay. There is a beautiful view from the rooftop terrace, and the building has two washing machines for doing laundry. The apartment is in a secure household building (front door with metal bars), and has an elevator access. The neighborhood is safe and calm, and a ten minutes walk from all the shops and boutiques in Palermo, a five minutes walk from several bus stops and the city bike service. Once a week there is small local market just down the road with fresh vegetables and produce for sale. Martin and Anabel are wonderful hosts, speak perfect English (they spent a lot of time in the US), and always prompt in communicating and very helpful in providing directions and tips about Buenos Aires. During my stay they replaced the old air conditioning with a brand new system which works perfectly and is very silent. To answer about the reviews below complaining about the train noises: indeed there is a train that runs nearby, and the first day or so it takes some getting used to, but after that you don't notice it anymore.
