We're a family of 5, with 3 kids under 12 so wanted an apartment that was central but also not too noisy at night - Av. del Paral-lel is 10 mins walk to the port, 10-15 mins walk to the bottom of La Rambla, and the tube is direct to the Nou Camp for football fans!
Totally recommend the apartment - 4 big bedrooms, a fully equipped kitchen, 2 bathrooms - and Carla was lovely - really welcoming, and super helpful with places to visit with kids and recommendations of local restaurants.
Would totally recommend booking, for families or groups - lovely place, lovely vibe.
