Restaurants, Banks and a market are within the block. Taxi is always available out front due to a 5 star boutique hotel across the narrow side street... the Host Ferran and the Concierge Mauro are fantastic...check it out on Trip Advisor!! Well worth considering as a base while in Barcelona. Better yet,send Ferran an email....You will have a personable and knowledgeable friend waiting for you in Spain!!
