This apartment was absolutely perfect. We are a group of 6 which was our two children (12 & 7), ourselves and the grandparents. This apartment worked so well for everyone. It was a really flexible space, the bedrooms were lovely, the decor was superb (it's as good as it looks in the photo's).
The area is great for families, lots of lovely restaurants, a great bakery, gorgeous grocers. It was really easy to get into the centre. There was a tourist bus stop and a metro stop about 10 mins walk away. We did the tourist bus for 2 days and it was a really great way to get around Barcelona and see all the areas.
