It's 3.5 star rounded up. Why? Way too touristy. I traveled here last in 1998, and Barcelona was my favorite city -- and I visited 10 European countries. It was charming, and not overcrowded -- 5 stars all the way. In Dec 2017, I traveled here again, and it was overrun and very touristic. This effects the food, every Gaudi thing, sitting and watching -- I'm done -- 3 star at best.
Things to do: 5/5
Safety: 4/5
Cleanliness: 3/5
RESTAURANTS -- Isabella's, Patron, Toto were my absolute favorites. Others nearby the Las Ramblas/Passeig De Gracia area: La Poma, Casa Guinart, Mussel, and bakery/coffeeshop, Il Caffe di Francesco - Pau Claris.
GAUDI -- All of the Gaudi structures are a must see: Basílica de la Sagrada Família, Casa Batlló, Park Güell, Casa Vicens, Casa Milá (La Pedrera), Colonia Güell, Casa Calvet, and Cascada Fountain at Parc de la Ciutadella.
LAS RAMBLAS -- Must see ONCE, but way too touristic and not worthy unless you need to get to a nearby place.
MERCAT LA BOQUERIA -- A super high-end, expensive, but amazingly beautiful outdoor market. Many eateries with hard-to-get counter seating for seafood, meats, and other grilled items. Truly a spectacle, and a great experience. Surrounded by mostly touristy restaurants, Casa Guinart is an exception -- great meal.
TABLAO FLAMENCO CORDOBES -- Amazing Flamenco show. Totally recommend! Make certain you get good seats where you can see the feet of the dancers.
HOTELS -- I recently stayed at Hotel Catalonia Passeig De Gracia, and it was nothing short of wonderful. Super clean and well decorated. The staff was super friendly, English-speaking, and very helpful.
