Amazing hotel!! Great value for money (off season). The room was very clean, beautiful view of the mountains, the staff was very nice and helpful, the dinner was great but a bit pricey, free welcome drinks and the outdoor pool is a fantastic addition to the hotel!

We had an amazing stay! Everything starting from The beginning was wonderful! The staff is very nice and welcoming. The room is clean and the view is astonishing! We chose to dine one night at the hotel - very tasty and fresh food. A bit expensive though. The breakfast is great and fresh. Big choice and a very good coffee. The heated infinity pool is beautiful and all the sauna area is relaxing and clean. We took the cable car from Sieser Alm to the top of the mountain - recommended experience , but a bit expensive for one person. If you ask - the room can be cleaned every day. If you search for a place to clean your mind and relax body and soul - this is the perfect one! Hope we will Be back :)

Amazing hotel, it’s nice, clean and well decorated, it has everything you need for a relaxing holiday. The pool is nice, water temperature is perfect. The relaxing area is great too. Breakfast was delicious. The staff were very nice and welcoming. Location is great, close to the main attractions in the area. The room(apartment) is spacious, has everything you need in it and pretty clean. The view from the balcony is breathtaking. Loved our holiday in this hotel, would definitely recommend it to anyone exploring the Dolomites.

Nothing!

Hotel is facing the sun, we had sun all week so my favorite time of the day was morning with coffee on the balcony and sun. Heavenly! The spa and swimming pool are very clean, the apartment also. Loved the relax room, very beautiful view and very comfortable lounges. The music tablets, what a good idea! We had dinner in the hotel restaurant and the waiter was very polite and professional, the food was also very good. Compliments to the Chef! The hotel is well connected with town and cable car, so it was easy to go skiing. We spent a week skiing and relaxing and the hotel is ideal as a winter holiday stay. We love Castelrotto area and we will come back!

We loved everything about Sonus Alpis. The hotel is specifically designed to pamper all guests by providing multiple relaxation options including a gorgeous (warm) pool, spa, sauna and a wonderful wellness room where you can thoroughly relax with the aid of classical music. The staff are most attentive. The breakfast selection is brilliant. The welcome drinks and snacks unexpected bonus. And the view? Absolutely magnificent. PS May is a brilliant time of year to come. Beautiful, great weather, picturesque snow but not crowded. One day, hopefully, we shall return.

We used this as a place to relax after 10 days of hiking through the mountains. And it was perfect. The pool/sauna area was wonderful! The lobby lounge was comfortable and peaceful. The young man that came to practice the piano was very talented! And the young man at the front desk was extremely helpful and accommodating. From making reservations for us to serving alperol spritz’s by the pool! The room was comfortable and clean with great views. Breakfast was delicious. Big buffet and made to order eggs. Dinner was a bit expensive but worth it.

We had to leave

We had a wonderful experience! The staff was extremely kind and helpful with everything we needed. The breakfast was rich and indulgent (worth mentioning that the coffee was excellent too!). The rooms were clean and quite spacious. We really enjoyed the spa facilities – there’s a wet and dry sauna, and the outdoor heated pool overlooks a breathtaking view. We’ll definitely be coming back in the future!

Was very clean and comfortable

Excellent hotel ! Beautiful mountain view, large and comfortable room, warm pool and great saunas. Breakfast is amazing, everything is homemade, variety of fruits and local jams, gluten free options. Live music on the weekends. Skiers is only 10 minutes away. Will definitely come again.

The front staff was really friendly and helpful with hike recommendations. The breakfast was the best we've had on vacation with so much fresh fruit. I also love the pool and all the areas to relax. A very thoughtful experience.

It took us a few days to realize it's possible to walk into town (30-40 minutes on paths) so at first, we thought we always had to drive and park which wasn't ideal.

The view was incredible. The spa facilities were also amazing and very relaxing. Our room had a spectacular view as well.

The restaurant ambiance didn’t really fit in with the rest of the hotel but we stayed in the shoulder season, so it may change with a full hotel.
