Japis was waiting for us at the apartment when we arrived and did a wonderful job of showing us around the flat and giving us some extra information and recommendations about the city. The apartment was very clean, cozy and equipped with everything you would need. The location is perfect. We got just about anywhere we wanted by foot and all the main streets are just a few blocks away. The apartment is also surrounded by a number if delicious bakeries, cafes and restaurants. Our recommendations would be: Panaria (just downstairs, i.e. in the exact same building as the flat), which is a wonderful bakery with fresh bread, pastries and delicious coffee; Brunch&Cake - a great place for a great breakfast, lunch or dessert; Etapes - a very good place with authentic Spanish cuisine. The recommendation (from Japis) of Reserva Iberica for jamon was an excellent one as we thought it was the best one we ever bought.
So if you would be looking for a place to stay in BCN then don't hesitate to choose this apartment as it would be the perfect choice!
