Jose absolutely deserves the "super host" tag. He was super flexible with checkin and checkout, even helped us with arranging our the taxi to the airport + basically helped with anything (and beyond) if we had an issue. He was very responsive, too.
As of the place: it's VERY baby-friendly. We stayed here with 2 kids (3 years old + 7 months old), both of them enjoyed the place very much... especially the dedicated room with all the toys and the special baby floor, etc.
Before I booked the place, my only worry was that I never stayed in an apartment that had a front door right to the street. But my worry was unnecessary: as it turned out, this became a very great feature of the apartment, especially with the baby-stroller -- it was super easy to access the apartment. Also the neighbourhood was really peaceful and friendly. (Great coffee/icecream place right next corner!)
It's also easy to access quite a few great parts of the city: beach, Calatrava park, Gulliver park, downtown, etc
