My mum and I had the pleasure to stay a week at Iga's place. It looks exactly as on the pictures, very stylish and only recently refurbished.
The location is superb: airport bus 46 is a 10min walk, old town and Montjuic only a stones throw away and lots of nice cafes and gastrobars around the corner - you'll find everything you need within easy reach.
The apartment itself sports everything you need, the kitchen is fully equipped although we didn't really use it. Bring slippers as the floor can be cold (at least in winter). There's wifi and towels, even shampoo and sunscreen, which I found very thoughtful
