Nicely located flat, in a quiet neighborhood, close walking distance to underground lines (4 stations away from Sagrada Familia) and main train station.
It was very clean, well equipped and has good amenities.
So, it's a good place to stay to visit the city if you don't intend to spend too much time "home". Indeed, it's in an old building so is a bit noisy but, nonetheless, I would recommend it without hesitation !
