Do not book anywhere else. This place is spacious, clean, has a beautiful private terrace and is walking distance to many of the best attractions. Metro line is also only one block away. The have a washing machine so you bring have to packtons of clothes and a grocery around the corner so you can buy food, toiletries, snacks, etc. They have a full kitchen with everything you can possibly need to cook a great meal if you want. I would stay here on every trip to Barcelona from now on
