El resto muy bien, cama cómoda, mobiliario correcto, limpieza de 10 y personal muy amable.
I didn’t like the spa very much. It was small and overcrowded, and you practically had to run to get under one of the jets.
El spa no me ha gustado mucho, pequeño con mucha gente,que casi tenías que correr para coger un chorro.

8 David October 2026 The rating is boosted by the housekeeping team and the excellent location.
La calificación mejora con su equipo de limpieza y la excelente ubicación.
The lack of attention from the reception staff and the quality of the breakfast for a 4-star hotel—you expect more. But you get what you pay for!
La poca atención del personal de recepción, la calidad del desayuno para un 4 estrellas, tienes más expectativas, pero relación calidad precio es lo que es!

10 Maritxu Travelled with family March 2026 It’s situated in a very quiet area but still close to many services. The staff are lovely. The spa area is wonderful and very well organised; that said, I recommend booking sessions when children aren’t allowed if you want to relax — it pains me to say that as a mother, but it’s not the children’s fault. The café isn’t very expensive considering the views and that it’s a 4-star hotel. Highly recommended.
Esta situado en una zona muy tranquila pero a la vez cerca de muchos servicios. El personal encantador. La zona de SPA una maravilla muy bien organizado, eso si recomiendo coger horarios en los que no pueden ir niños si buscar relajarte, me da coraje decir esto como madre pero la culpa no es de los niños. Una cafetería no muy cara dadas las vistas que tienen y tratarse de un hotel de 4 estrellas. Muy recomendable.

9.4 Miguel Angel Travelled with  friends November 2025 The only slightly negative thing: if you walk to Viveiro it takes 35-45 minutes, and getting a taxi back after 22:00 is complicated. Everything else was great.
