The apartment is in a great location for visiting La Sagrida Familia and several of Gaudi's other buildings. It's a 20 min walk into the city or just a few minutes on the metro from one of the nearby stations.
The apartment itself is well equipped and clean. The hosts provide an abundance of information on local attractions and getting around and was kind enough to spend a good half hour chatting through options fir us to get the best out of our short stay in Barcelona.
We were sad we could not spend longer in such a beautiful city but would happily stay at this apartment again when we return.
