Elio and Wilken were greats hosts! They were very helpful with offering to store our luggage at their offices or directing us the Barcelona lockers. The check in was seamless; their colleague Conchita was waiting for us at the flat when we arrived and gave us a map and lots of helpful tips for the city. The flat is a nice neighbourhood with a great coffee shop and bakery just downstairs. Very central and overall a great place to spend the weekend. Thanks!
