Tincho was very welcoming and nice. The room is nicely located, close from the metro, in a district with nice restaurants and close to a nice shopping street. The flat was quite new, with automatic lights.
The room is a bit noisy though, as it's on the 2nd floor giving on a moderatly passing street. So if you're a light sleeper, be careful ;).

I would recommand this flat for your stay in Buenos Aires!
