I stayed at Nicolas' place for a week, enough to quickly feel at home and make his flat my own. Well designed and perfectly located close to many cafes and parks of Recoleta and Palermo.
Right around the corner is Ol' Days, the ideal place to work from, great coffee and good breakfast. My office for the full week during the mornings. Also great coffee to be had at Placido, just a few blocks away. Food wise, 'La Querencia' was also nearby ready with traditional Argentine food.
Nicolas was very friendly and efficient and easy to communicate with, I'd recommend his place to anyone looking for a home from home.
