The staff at reception is super kind and very professional, always ready to respond promptly to guest's requests. The size and comfort of bedrooms are excellent as well as bathroom sizes and of course the amazing SPA in the basement. The restyling added huge value to this historical hotel with an elegant gate and the entire lobby and common area. The use of engineered marble on the floor, cladding, and table shows an accurate design that pays attention to combining innovative materials into a classic context.

I suggest improving the 58-degree restaurant overall and particularly the ventilation system. I suggest informing even on Booking.com presentation about the closure of the pool every Tuesday to allow customers to plan properly their stays.

Lovely place and the big thermal pool is wonderful! If you don't speak Italian a little difficult to get full information, but just keep trying, Most of the staff were lovely.

Was a little surprised to be charged €10 a day to use the pool – they said that booking.com bookings get charged but if you book directly through their site you don't get charged for using the pool.

Overall, the hotel exceeded my expectations. The room was clean and well-furnished, the restaurant 58 Gradi very good and not overly expensive, and the grounds are lovely. I went with my 10-year-old son and he adored the breakfast! I was impressed too, after having read some comments here that breakfast was lacking. Fresh fruit, sweet baked cakes, butter croissants, meat, eggs, freshly-made pancakes and even honey from the comb- seemed more like breakfast choices you would find at a large resort. The guest entrance to the Terme has many advantages including spa kit, pool beds in reserved area (which is much appreciated, seeing the other crowded sides of the pool) access to the jacuzzi and private changing area. Reception staff, restaurant and bar staff were very courteous and cleaning staff helpful with getting right sizes for the spa kit. Will be back.

Very nice facility, well kept. Staff extremely professional and friendly, except for Miss Gilda, absolutely unfriendly, inadequate and out of tune with all thebrest

The spa facilities were really unique. It took some discussion with the friendly staff to figure them all out but the thermal pool, massage and especially the natural grotto hot room were excellent. The restaurant was also quite good.

Our first room air conditioner didn’t work so we had one uncomfortable night. We were moved to a better room and everything was fine

The staff were so helpful and friendly. They did everything to make me feel welcome and looked after me the whole time. Great that the pool has a reserved area for guests that doesn’t get too crowded.

The only thing I didn’t like is that people are permitted to smoke at the pool, when you are trying to relax and get some drag air and sun.

Location near lovely Viterbo, kind service and comfortable premises are great for rejuvination. Fantastic thermal swimming pool, good breakfast.

Would have loved to be able to use swimming pool in the evening after 7PM as well. And not that this is a complaint, just a suggestion- written info about available treatments could have been also in English.

The breakfast was wonderful. The meals were all wonderful. The staff was beyond exceptional: professional, friendly, kind, at times funny, well trained, gentle, the best I have ever experienced in all of Italy.

The only thing I can suggest is to please clean the chairs in the dining room. A few were very dirty with hair and food on them.

The staff were very friendly, really professional. It had a very relaxed vibe. The room was spotless, the air con worked perfectly. My husband really enjoyed the breakfast. The thermal baths were very enjoyable. We were provided with towels, crocs and robes for the spa. We ate in Viterbo city centre which was a 5 mins drive away.

We enjoyed our stay. It was difficult to find fault with this stay.

A beautiful experience and will always be staying here. The hotel is so well furnished and very clean, the staff are trying their best to cope with everything I need, the pool is something extraordinary and must try. A beautiful spa too.
