LOCATION LOCATION LOCATION, that's pretty much the only positive thing about this place, espcially if you're beach person, as it's a 5 minute walk. However if you want to get all touristy with the mainsteam attractions (Sagrada Familia, Camp Nou, Parc Guell, All the Gaudi stuff) then prepare yourself for a long bus ride or a 15 to 20$EUR cab ride.
The unit itself is smaller than the pictures make it to be, there is A/C, but only to half of the unit, it could be a lot cleaner, and is cluttered with a lot of the host's belonging, in dressers and cabinets, stuff you wouldn't need to use. There was a bunk bed, but not suggested for anyone, my 9 year old had issues and he felt unsafe as it was flimzy.
I guess you get what you pay for, but I think with all the fees, this unit is a bit over priced. I wouldn't stay in it a second time for all the reasons mentioned above.
