I have to say Garcia's Place was one of the best experiences in our trip to Barcelona.
The location is fantastic, where only 3 minutes walk to the subway station (Sagrada Familia). The L2 and L5 lines can take you to all the places in the city.
You can also find many great dining places and restaurants around.
the Sagrada Familia is 3 minutes far by walk. Everyday when we came back we were always shocked by this master piece of architecture.
The apartment itself is clean and cosy. The balcony is great to have a drink and have fun with friends.
In a word, Garcia's place may be the best choice for you to stay at Barcelona and I will strongly recommend it.
