Nice, clean and cosy place with a great location near the Science museum and Oceanographic (Aquarium). There are many parks and playgrounds around this flat so if you have children you will find everything very convenient. There is a lovely breakfast joint around the corner called El Bar, which we visited daily and so all-in-all, a fantastic location.
Just note, if you do bring a car, make sure that it is no bigger than say the Hyundai Tucson. The underground parking is a little tight around the corners.
Overall, we had a great time. Recommended.
