The location was perfect. The hallways of building were graffiti filled, and it was a 45 step climb up a narrow twisting hallway so you will definitely get a good work out. I’m 62 yrs old and while my host was very kind, their life schedule was sleep in and stay out late so best for someone perhaps younger? The apartment is small, but if you’re not wanting to relax or stay in, it’s nice and central to most attractions. I loved Barcelona!
