Silvia's apartment is cozy and very conveniently located. The room she offers has a comfortable bed, and loads of cupboard space. There is hot water on demand, and the kitchen seems to be well equipped (I didn't use it much). It's a 5 minute walk from the metro station, 5 minutes from the beach, and there are many good restaurants and bars nearby.
Silvia was very responsive, and was flexible with checkin and checkout times. My stay was very pleasant in all respects.
