The appartment was exactly as expected on the description and pictures, which was the first (and important) point we noticed. The place is well situated, close to the public transports (Plaza de Espana is about 5 minutes walking), with a unique and quiet terrace offering a nice view! Everything was fine in the appartment: it was clean, fully equipped and roomy even for a 4-members family (they even provide a cot for baby if needed).
I would highly recommend it to other people.
