Since I had been to Barcelona before, I knew I didn't want to stay smack dab in the middle of the tourist area. Gracia is a lovely section of Barcelona that is more local and eclectic. Ana's place is very quaint; the highlight is the balcony! City center is not super close, but definitely walkable (25-30 minutes). My boyfriend and I took a taxi maybe twice during a few days time. I recommend checking out local eateries near her Air Bnb as you're guaranteed better food for a much more reasonable price than anything you would find if you stayed in the touristy sections (I.e. Las ramblas)
