While apartment is close to trains and Sagrada Familia it is not near other areas of interest. But pretty easy to get around. Bring extra adaptable plug in, we blew 2 while there which blew ele ctric as well, had to buy more . had to figure out how to get electric back when it blew out 2x and did not get response from owners when we let them know. Very noisy and busy street. Place was clean, and roomy, I had an issue with getting bit by some type of bug each time I got back into the apartment but my son did not, not sure what it was. Disappointed with lack of response once we arrived in Spain, much less then before we we booked. do homework on traveling from place to place, and for places to eat, none were given to us or suggested. Make sure you are prepared to possibly wait to get into apartment as it appears they own several and if people are checking in at same time they will try to arrange to get to you at time you are ready but not a promise, so will have to wait outside until they get there.
Over all it was ok. first time using airbnb and this was the second one we stayed at. first one was a little better, maybe this is the way it is with airbnb, not sure since first experiences, think I may choose hotels next time.
