Maria and her family are incredibly friendly and accommodating. When booking our reservation, the guest room wasn't free for our first few nights, so she and her daughter let us use her daughter's room- it was so kind. The house is always neat and you can ask her anything about the area. The neighborhood is in a perfect location for shopping, eating out, and sightseeing, plus the San Telmo street market takes place right outside their front door on Sundays!
