I stayed at Rosa's apartment with a colleague during a work trip. The apartment is located at the corner of the building and all rooms have direct natural light as all street facing walls are glass windows, which is a great feeling. Even working with the laptop during daytime felt as if it was too bright!! The apartment was also very clean with super comfy beds. I didn't meet Rosa but she was always responsive, and was flexible at check out. Finally, I'd just add that Gracia is my favourite neighbourhood in Barcelona. I would definitely stay again!! Thanks Rosa!
