We had a fantastic time in Juanan's little flat in Barcelona; the area is nice and quiet but still extremely easy walking distance to all the touristy hotspots (Sagrada Familia about a five minute walk). Some lovely restaurants and bars nearby that were recommended to us by our host, which we really appreciated - we ate tapas at two of Juanan's tips, and it was to die for.
The apartment has everything you could possibly need for a comfortable stay in the city, and the bed is extremely comfortable; I am actually missing sleeping in it since coming home! A wonderful apartment with an extremely helpful and welcoming owner: can heartily recommend.
