Very nice location overlooking a picturesque Barcelona street - some street noise, but nothing overly bothersome unless you're a very light sleeper. The apartment is well furnished with simple but usable IKEA furniture. The apartment definitely feels like a dedicated rental and not someone's home.
The location was a perfect home base for our family vacation, just far enough from the more touristy areas to feel like you were getting a more "local" experience but convenient enough to easily get to the major attractions. Also a very short walk to some exceptional bakeries and coffee, which makes for a nice start to the day.
The hosts also were kind enough to stock a small selection of children's toys in one of the closets, which was a big hit with our young son.
