Could not recommend Mires and her flat more. The apartment is centrally located but not in the middle of crazy traffic or tourists. Easily walkable to old town and only a block or two from a metro stop. The apartment itself was perfect for myself and a friend and we absolutely LOVED the balcony. We spent every evening out there at some point, usually enjoying some cava and watching the sun set. Mires was so kind and we had a small WiFi outage but she worked tirelessly to get it back up and even came over and offered her cell phone hotspot when we needed to hop on Skype for work one night. Definitely the place to rent in Barcelona!
