What a lovely stay! The apartment was bright, spaceous and very clean, just as described on the pictures. It is run by an agency, so we were provided with everything we needed. Also for 6 grown persons it works out, as the sofa can be converted in an almost equivalent bed.
The location is also quite good, between Montjuic and the beach promenade more or less.
Check-in and check-out was easy and the agency representative we got to know was really friendly and helpful.
Overall, I would give this apartment a clear recommendation for everybody visiting Barcelona, be it with family or friends.
