Taking my mother (70s) to Barcelona in the fall. We will walk/subway/taxi to various locations (walking as much as possible). 4 nights. Looking at lodging near Arc de Triomf (roughly Rda. de Sant Pere, 41, Eixample) and near Museo Geológico del Seminario de Barcelona (roughly Carrer de la Diputació, 231, L'Eixample). We haven't picked the exact hotel or lodging, but saw a few in these two areas. Is there much of a difference between them? Are both good options? Prefer safe, close to restaurants and the metro; less about night life and the beach.
Thank you kindly
Jana
