My experience with Imma was wonderful! I could not have wished for a better host and better place to stay. The Gracia neighborhood is very central especially with the 39 bus outside the door and the metro a few mins walk away. But we found that you did not need to leave the neighborhood to be completely immersed in Barcelona's culture! Imma was very hospitable and extremely laid back with her home which we found extremely comforting.
I would love to go back and would stay no other place!
