Raimundo's apartment is situated in the old part of Barcelona, on a quiet street. It is conveniently situated, short walk to La Rambla, the Gothic part of the city and a manageable walk to other attractions in Barcelona. We would advise taking the Barcelona Bus Turistic, we booked for two days and saw most of the popular attractions. The buses are every ten minutes, we found it to be an excellent service and a good way of getting around the city. Places to eat, as recommended by Raimundo, La Candela - tasty, well presented food. I would recommend the "Summer Wine".
Another recommendation is Elsa Y Fred, beautiful food, excellent choice and presentation. Really relaxing, pleasant decor.
Breakfast and an evening meal, we went to Casa Lolea - situated opposite the apartment. Raimundo was very accommodating and helpful, he has lots of advice where to visit if it is your first time in the city. Would highly recommend.
