My family of 6 (two couples and two singles) stayed at Yök for 4 days. Perfect location, 25min walk to Sagrada Familia, 5min walk to Arc de Triumph, lots of wonderful bars and restaurants near by. Apartment was very clean and tidy. Typical city noise in the apartment, but nothing overly loud or disruptive. It was also very nice having 4 beds and 4 full baths! We met Petz and Sandro, and they were both so friendly and helpful. If you are looking to stay outside the touristy gothic quarter but still within a nice walk to all the main sights, I would recommend staying at Yök!
