The location of the flat is absolutely fantastic. You are meters away from av Diagonal and passeig de gracia. Although you have a great view on Diagonal the flat is not noizy at all.
The overall condition of the flat might be better. Some of the furniture pieces and sanitary ware are worn out and require restoration. But I believe the owner will do something with it.
The flat is big and well planned. Good for a family of 4.
