Staying at Daniela's place was awesome, the room was even nicer than what we though and the apartment it self is super cool full of retro details with a lot of taste, and it has the best views of the whole building. The area is very quiet and only 3mins walking distance to the metro or any bus to get to the seaside. Daniela is a great host, she speaks English, French and Spanish (with both Spanish and Argentinian accent ;D) and will help you out with anything you need to get around the neighbourhood or the town and make your stay as good as possible. I will for sure stay at Daniela's next time I go to BCN. All the best Daniela!!
