Silvia has an amazing soul, and is a wonderful host. She accepted me into her apartment last minute, and when I arrived to Spain, she spent plenty of time explaining all the important sites to me. I really appreciated Silvia as a host, especially since I made my trip without any previous plans and some of the places I ended up visiting I would've not known about without her guidance. Her apartment is centrally located, very close to the metro, and it is pretty easy and safe to get around everywhere.
