This apartment is exactly as good as it looks. It is clean, well organized, and extremely comfortable. For me the location was perfect. I love that it’s on a pedestrian way with lots of cafés and restaurants, and super easy to access the metro. The balconies and their views are wonderful. If you are an exceptionally light sleeper, you will hear the street noise at night including car horns and people out and about walking. So if that bothers you maybe bring earplugs! Also during the day there was construction going on in one of the other apartments, and that was pretty loud and had a lot of vibrating. My friend that was staying with me stayed on the pull out couch, and she said it was extremely comfortable.
Truly this is a great place from which to explore Barcelona!
