We spent a week here from the 14th September and loved it. This is a modern hotel, fresh, clean and bright. The staff are really helpful and friendly and the whole ambience of the place makes for a really pleasant place to stay. Sometimes it is the subtle things that make al the difference to the experience (handing out a free slice of melon for people sunbathing around the pool). The hotel is a bit out from Viarregio so the complimentary bikes are also a nice touch, although there also a bus if you want travel that way. We stayed by the pool when in the hotel but the hotel is across the road from the beach if you prefer that. But note that like most Italian beach's you have to pay for sunbed hire to use it. We never used the spa but it was popular and people said it was a nice place to relax. There is also a garden area covered by trees for people who want to sit away from the pool.
We generally eat out in the evenings but this time the food was so good that we stayed in and then relaxed either on the rooftop bar or on the loungers around the garden.
We used the hotel as a base for travel and used local transport to get around. Visiting Pisa and Lucca by bus was easy and a lot of fun to do. Florence is also possible.
In summary like previous reviews all I can do is endorse them and say this is a great hotel.
