We recently stayed 7 nights at Alex's apartment in Barcelona, and we can see why it's booked out so far in advance!! This was our first time staying with Airbnb and it was a fantastic first experience! The apartment was clean, roomy and very modern. The location was brilliant, not too close to the main areas but not too far away either, about a 15 min walk to La Rumblas was perfect! We wished we had discovered the train earlier as it was two or three blocks away connecting our apartment with the main attractions in Barcelona.
Alex is a lovely man who kindly waited at the apartment for us after our 30 hour flight, and came earlier when we needed to catch our flight out of Barcelona. He recommended some great restaurants too, which we we went back to one of them twice!
We definitely recommend this apartment to anyone wishing to stay in Barcelona.
