You will be hard-pressed to find a better host than Elisa. She was attentive prior to my stay and throughout. My friend decided to come join me in Barcelona for a few days, and Elisa went above and beyond. She found a place right near her apartment for my friend. Elisa is warm and friendly. We had great conversations, and I hung out chatting with her and her boyfriend until late at night. She made sure that my taxi was confirmed for 4am so that I would not be stuck without transportation to the airport at that hour.
Her place is nicely decorated and comfortable. It is close to Sants Estacio. I would definitely stay with Elisa again when I return to Barcelona.
