Rosa is a great host, I stayed there for 3days. She is like a mom, when I arrived there Rosa caught cold but she was preparing bread, wine and Jamon for me. It was around 4 in the afternoon, so she thought I might be hungry after long flight. The location of the Rosa's home is walking distance from city center, and it is quite and very clean. I bought metro ticket, but actually i didn't use it a lot. I recommend Rosa's if you want to feel at home during your travel
