Sergio's place is exactly how he describes it. First before we booked we asked him if he had a crib for our baby and he didn't. A few days later he emailed saying he bought one so we booked with him immediately. Then he met us there when we arrived and had coffee, tp, and other candies/drinks for us to enjoy during our stay. He even bought our children books and toys to enjoy during our stay. There are 3 little stores within 4 blocks of the place and the subway line is at the end of the street. Sergio had subway cards that you add money to and can use during your stay. Made exploring the city easy. He had a little book with information about his place but also things to do or places to eat in town. His responses were extremely quick. I would highly recommend staying at Sergio's. I know we will when we come back to Argentina!
