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.

8 Miguel Ángel April 2025 The hotel is well located, the room is spacious and clean, and the breakfast is sufficient even though it is not splendid.
El hotel bien ubicado, habitación amplia y limpia y desayuno suficiente aun sin ser esplendido
The worst thing is having to walk 50 metres down the street to access the spa, and the spa is quite small although the staff is very friendly and will solve any problem that may arise.

The spa you have to leave the hotel premises to the street in a bathrobe to get to the spa. The restaurant menu in the hotel's QR code has different prices than the menu when you sit down to eat.
