Carlos Daniel was a perfect host, and his place is excellent. You won't find many places so well located as Carlos Daniel's in Buenos Aires downtown: the building is a few blocks away from essential landmarks, very close to subway stations and venal bus routes/stops, and close to several places for eating and drinking (all meals, all kinds of food). If you're a kitchen person, although, check the appliances available, as they may not be suited to all your needs. I really recommend the place.
