Isidre's spot in Gracia is wonderful (but more importantly, so is Isidre!). He let us check in early -- like caught a night flight and arrived at 8 AM early -- and was warm and welcoming when we arrived, travel-weary, but with seemingly endless questions. He answered them all, marked up a map with recommendations, and then set us loose in the city. Isidre also checked on us while we were there via WhatsApp to make sure we had everything we needed, including info about a metro card that we ended up getting. He found us a business center to print our boarding passes when we asked about that. He's a truly wonderful person. His place is great too -- super clean and functional with everything you need right there. We made coffee, did laundry, got awesome sleep ... :) And Gracia is central -- a good distance away from the hustle of Las Ramblas, but within walking or subway distance of all the places you want to go. Stay here; it's great!
