We really recommend staying at Casa Humberto! The apartment is really nice (even better than the photos). Large, airy, classy and clean. It has 3 separate bedrooms. It’s in colonial style with nice furniture and quirky details. It’s located in the middle of beautiful San Telmo on a quiet street. It has good facilities like air conditioning, coffee maker, mate (y yerba) and basic food (spices, oil, etc). Guille was a perfect host. He answered all our requests quickly and was really helpful during check in and check out. He was also available for help and tips during our stay. We will definitely check if Casa Humberto is available the next time we go to BA.
