Pleasant staff and a clean, though small and basic, room, with breakfast included.
However... DON'T stay up here if you want easy access to Vigo-Guixar station - Vigo has two main rail stations: this hotel is quite close to the other one, Urzaiz, but many (most?) longer-distance trains go to Guixar which is down the hill closer to the water-front. The walk up from Guixar to the hotel is quite lengthy (probably about 25 minutes?), uphill, and I definitely would not recommend what looks from maps (and smartphone/internet planners etc.) to be the most direct route: it takes you through some areas that are to say the least not very salubrious and which even I would avoid after dark. If it is just an overnight between trains, there are equally good and more convenient closer options - even if the staff might not be as welcoming as at the Celta!
