I was more than pleased with my stay at H10. The staff went out of their way to ensure my stay was excellent. Centrally located to most Barcelona sites and shopping, and two metro station within a block. If I had any complaints at all, I would say the walls are a bit thin, so it's quite easy to hear noise from the next room over. My room was upgraded to a suite, which was huge by European standards. The lobby and decor is minimal, modern, and chic. I will be back to Barcelona and won't hesitate to book with H10.
