The staff in particular Sandor, Rolando and Jorge, were fantastic, so knowledgable and helpful with advising us on places to visit, the best places to eat and organising tours.
It was so well maintained, clean and the breakfast and bar were wonderful, as was the environment, also a great location within close walking distance to everything.
As with all of Cuba the electricity was a bit patchy (no fault of the hotel) just the way it is.
I highly recommend Hostal Balcones Muralla.
