Spent the Winter holidays in Barcelona with our adult children and their partners (6 people). The flat was as advertised in the heart of Barcelona with most popular sights, dining, stores/shops, metro access, etc within a couple minutes walk. We never ate in the same restaurant for the duration of our stay and could get fresh groceries, bread, coffee, etc within a couple minutes. Very convenient, with easy access to the entire city.
The space was comfortable, private and had a nice outdoor balcony that we took full advantage of. The kitchen was sufficient to cook for and seat 6 people, but lacked basic cooking tools (e.g. measuring cups, cutting board, mixing bowls etc). There was plenty of space with 3 good size bedrooms and 2 1/2 bathrooms. The bathrooms could use some maintenance: the shower in the bedroom is not operational the other two mostly functional, but had issues with loose / broken fixtures, etc. A little additional investment and maintenance would go a long way.
