Overrated for a 5 Star hotel

For a five star hotel there was no 24hr room service. Bar closed at midnight. Breakfast was very basic with limited choices. If you wanted a boiled egg that would cost you an extra 5 euros because it’s not included in the breakfast buffet. For dinner the quality of food was sub standard for 5 star hotel. The food looks and taste as if it was microwaved for charging at 5 star prices. Staff was very helpful and pleasant but all in all I don’t think this should be 5 star hotel and should have their star rating reviewed.

Very nice hotel. Staff were extremely friendly. Our disappointment is that they turn off the air conditioning at night and recirculate the outdoor air. It’s just not comfortable enough for sleeping. Also the WiFi in the bedroom is very weak to non functional. It’s too bad because it’s a beautiful hotel, beautiful rooms and great and tranquil setting. However because of the air conditioning we will not be staying there again

It's a wonderful hotel, we had a juinor suite which this time overlooked the other side of the hotel away from the road. The spa was lovely we used it nearly every day and some days we had the indoor pools to ourselves. The last time we where there was last year in October. We had breakfast on the outdoor terrace which was really lovely.

OK Hotel...doesn't feel like Tuscany

The hotel is very clean. Bed is comfortable. The sulfur/mineral pool is very nice. The hotel is far from everything, which can be good/bad depending on what your needs are. For dinner and breakfast the restaurant is OK, but not great. For lunch we did not enjoy the food so we had to find places to eat which were around 30 minutes drive. At check in you are required to sign a massive contract with the hotel which I found quite odd. When arriving I asked for restaurant, cooking class and other recommendations of things to do. The receptionist said she would have something for us the next day. The next day when I came to ask the reception for a reply they said tomorrow there will be an answer. After that I just used Tripadvisor and four days later still no message from the reception.

What a beautiful retreat!

This was one of the best places we stayed at in Italy! The grounds are gorgeous, the hotel is impeccably clean, the service was courteous and the room was amazing. We lived it so much, that we extended our stay to one more night. We really enjoyed the spa as well! The only drawback is that it was hard to find anyone from staff in the spa/pool area when we needed to ask some questions. Other than that - we loved the place and would stay again.

A great place to go again!

Very nice facility and good service. A great hotel with thermal spa and they have 6 pools including 2 outdoor pools. It’s a bit out of the popular route but definitely worth the drive. I’d like to go again in sometime. It’s better to go on weekdays when it’s nice and quiet.

really great hotel in a location all on its own (can be good or bad depending on what you are looking for). Clean and modern. We stayed in one of the Suites and it was lovely although the view was looking over the employee car park so not completely ideal but still very nice.

Great place but beware of spa hours!

The facilities were very nice, the room was extremely clean, and the bathroom especially was great! It all felt very spa-like. My one problem, which was quite frustrating, is that the spa and all pools close at 7 pm -- on weekends too, and at peak tourism season. We arrive at 6:30 on Saturday evening, and didn't have any chance to use the facilities until the next morning. But, due to check-out time, this meant that we only really had 1.5 hours to take advantage of everything! It was really disappointing, and also the pool hours were not posted on the website. So, I would recommend getting there early, or staying 2 nights to avoid this problem! Otherwise, the place is great and the service was friendly.

Sleeping on the M25

Described as tranquil this was anything but. Apparently the hotel was fully booked and thus we were allocated the room located at the front of the hotel which was feet away from the main road. Due to arriving at 8pm after searching for alternative accommodation we realised it was too late to relocate and rather than sit in a room where we had to raise our voices so as to hear each other we went to the hotel bar. Considering the hotel was 'fully booked' there were three people in the bar, it was just before 10pm! Yes the room was decorated very nicely but this was the only nice thing about this awful stinking inconsiderate hotel. The door to the outside balcony did not lock and looking out on a main road, where they're building a new fairway/bridge is not my idea of a relaxing and tranquil stay. We left the next morning and drove up to the beach past Pisa and spent our final day of our trip relaxing on the beach. The hotel should not be allocating anyone to those rooms at the front. I would not be surprised that they do this to make more money as people leave early and thus the rooms an be re-let. The word disappointing is insufficient to describe how we felt about this 1960's motorway hotel.
