Ferran's place was idea for my recent solo trip to Barcelona. It's just as described, a short walk from the metro station and with a wide range of restaurants within easy reach. If La Rambla and the harbour are a short walk away if you like the touristy stuff...
Ferran was the perfect host, always available when I needed info.
I'd recommend this apartment to any couple or family with children - the second bedroom has bunk-beds so not suitable for more than 2 adults.
