Lucy's apartment is incredibly located. A short walk to Placa Catalynya, the Catedral, Barri Gotic and so many other places. As far as location goes, you won't beat it. Like the other reviewers have noted, the apartment is in a Plaza in a busy shopping area, so there is some noise of an evening but it's certainly bearable, especially if you have ear plugs. Lucy is a great host - very friendly and helpful, happy to let you do your own thing, but also invited me to join her and some friends for some wine and snacks before they went out. As a solo traveller I felt safe, comfortable and very at home in Lucy's apartment. She had a fan to deal with the scorching Barcelona summer at night, coffee and breakfast available, and recommendations for places to eat nearby. Overall i had a great stay!
