Kilian was the best host I had throughout my three city tour of Spain. He was not only responsive, but professional. He not only met us in person to check-in (so many Airbnb hosts don't), but also allowed us to store our bags earlier than check-in while the apartment was being cleaned. He runs his apartment like a high end hotel, but provides the local feel that makes AirBnB so great. The apartment was very comfortable, clean, and just like the pictures showed. Gracia is a great neighborhood to explore Parc Guell and see the quieter side of Barcelona. The neighborhood is a bit of a ways away from the "traditional" tourist sites of Barcelona, but it was a nice change of pace. Also, the apartment in right in between two main train lines (about a 10 minute walk to each). Overall, I would highly recommend staying with Kilian. He's a great host with a nice apartment.
