I spent a week at Tincho's Belgrano apartment. He is a helpful, responsive, and accommodating host. Truly excellent!
The location was perfect for my needs and I loved it: Walking distance to all public transportation, charming small stores and family homes in the mix. Easy way of learning how people live and interact in the middle of a very large city.
Considering the apartment is 3 blocks from Cabildo (the main Belgrano avenue!), the apartment is very private and quiet, facing a street with little traffic (and none at night).
I thoroughly enjoyed my Buenos Aires week!
