I loved my stay at Jose Manuel's apartment. The location could not be better in my opinion: next to all the cool restos and bars of Born, the beach and the relaxed energy of Barceloneta. New, clean, perfect, all equipped with great wifi and Air Cond (which is rare but important in BCN, it can be very hot). Jose Manuel is a perfect host, he's genuinely caring and answers rapidly any question you might have.
When I will return in BCN, I have hard time imagining myself going somewhere else. It felt like home.
