Julio's apartment was just like on the pictures, modern, bright, well equipped. When we arrived, Julio's friend met us, but we also had a chance to meet Julio, who is an excellent host, always available and ready to help. The first day, we had a small problem with the heating but Julio immediately sent the technician to resolve the situation. The apartment itself is located halfway between the historic center and the "Ciudad de las artes y las ciencias", so it is ideally positioned for exploring the city. We don't needed public transport, except when we went to Bioparc.
I really recommend this place and host as well!
