We just came back from a 5-day stay at Pablo&Paz's and the accommodation exceeded all our expectations. The apartment is so cozy, very beautifully furnished and well equipped. I particularly loved a french press and the lightning, both natural and mood, and my son appreciated Netflix :) The hosts were very warm and welcoming, and the communication was a breeze. They provided us with all the information for smooth check-in.
If you're looking for a charming yet central place to stay at while in Barcelona, look no more. Pablo and Paz's apartment is exactly that.
