We were definitely happy with our stay!! We just happened to know that for a very small amount more we could have stayed in newly refurbished Riazor where we perhaps had less services available but a more relaxing newly refurbished overall environment, stylish relaxing breakfast, beach views...
Best things about Blue Coruña in our opinion: Staff & service (drinks & snacks in the lounge, bikes to borrow, parking arrangements ...), location close to old town and shops, quiet
Minuses for us: Some of the furnishings in bedroom and lounge could be modernised for a more inviting mood when you want to rest at tour temporary home
