It was my first time in Buenos Aires and I stayed in Joachin's apartment for one week. The apartment was exactly as advertised. Everything was like new, very clean, and in good working order. It has good internet and air conditioning and is quiet. The apartment key is a bit tricky at first, but with practice is fine. I enjoyed staying in Belgrano. The neighborhood is walkable, with many parks and markets (I especially liked Tina & Co, a few blocks down on Mendoza) and lots of gelato shops. Joachin was always helpful and friendly. I would stay there again and I recommend this apartment to others.
