Our plane arrived in Barcelona at 1am with a 2-year old toddler so flexible check in was a priority, and we were happy to find that check-in was a breeze even after a 17 hr long plane ride, it being on the entresuelo floor(1/2 floor=few steps) with an elevator was a big plus too since we’re using the stroller often! Frederic’s apartment made us felt at home right away, and the muffins he prepared for us was a life saver for our hungry toddler the next morning. The place is extremely walkable to major metro lines, and super convenient with a supermarket right across the street and bakeries/fruit stands/tapas around the corner, their office is also right downstairs which is a plus if you’ll need to store luggage. We recommend Frederic’s place 100%, it was a nice peaceful break from the circus of Las Ramblas but still easy to get around!
