I was rather confident based on the many positive reviews, and sure enough, everything was very much as expected. The flat is nice and practical, clean, everything as advertised, the washing machine was a life-saver with kids. The kitchen was just right for occasional cooking for the four of us.
Jordi warned he'd be out of town and we were welcomed by his friend Aurora. Jordi was very responsive, friendly and helpful in the multiple before and during the stay as well as when we met him in person the last day. He also volunteered a place to leave our luggage before going to the airport and took care of booking a taxi for us.

Getting there in a taxi on the first day was a bit of a challenge due to the many many one-way streets in the neighborhood. You'll see that for yourself if you try planning bike itineraries. Speaking of which, if you want to move about on bike, it's a slight climb to get to Gràcia but nothing insurmountable (80m elevation gain total from downtown). We found cycling to be our favorite way to visit the city and get a feel for the atmosphere.

Gràcia is really really nice place to stay at, much better than living in the more touristy areas. It's lively yet quiet, everything within 5 minutes walking distance including shops, nice bars and restaurants.

All in all a great booking experience, we loved staying there and have nothing but good memories from the trip.
