Stayed for four nights. Lovely hotel with a good restaurant. Quite a long walk to the centre of Pisa but there is a bus from outside the hotel (no 6) which goes to the Central train station. A good day trip from Pisa is a medieval town of Lucca 25 mins on the train 6 euros return. A good hotel for overnight stop for Pisa Airport as only 5 minutes. Recommend Osteria Bernardo - fab food and wine list.

Stayed here in Sept/Oct 2012. The hotel is a bit out of town but only 15 minute walk to Field of Miracles. Rooms are spotlessly clean and reasonable spec. Not 5 star but a good 4 star.
Reception helpful with room requests and taxi booking. Bar and restaurant staff generally good and helpful. We only encountered the "ladies of the night" once during our stay and they are down on the main road from the hotel. Didn't use the pool or the spa but both looked fine. Ate in hotel once and food quality very good.
If you get this at a good price you can't really go wrong. It's €10 to the train station for Florence, Siena, Lucca etc and €15 to the airport.
Loved Pisa, Loved Italy (again!)

Firstly our room was not upgraded even though I had email proof of my upgrade, which I had agreed to pay for. The receptionists were very abrupt and said I was wrong. Then they went on computer and gave us keys to a musty smelling room. Our food order was wrong in the restaurant so my fiancé ate first. I didn't bother 30 minutes later. The new room was nice enough in the end but not as nice as we hoped. The cleaning products were not replenished daily. Not a five star feel. Not welcoming. The customer is not always right.

Very handy for the A11/A12 and the airport, so great if driving and looking to stop off before getting a plane the next day. Very large car park too.
Staff are really nice and welcoming, and very helpful if you need advice. All spoke really good English, so this is a handy hotel if you don't speak Italian. The hotel is also a short drive, or about a 15 minute walk to the leaning tower, though this is through an underpass which may spook some people late at night. The main area of Pisa is another 10 minutes walk from the tower, so although the hotel is on the outskirts, nothing is particularly far away.
Other plus side was that breakfast was really good - usual buffet breakfast, but well above the average even though the fruit juice machine dispensed surprisingly low quality juice.
Only down side, the bar didn't have any Italian beer - just Becks, though they did say they had sold out due to the conference which was on that day, who all seemed to be dining in the hotel.

In Summary, great place to stay, easy option if you have a car, and best of all, if it's a rental as there are two petrol stations round the corner on the SS1 (Strada Statale 1 Aurelia), so you can fill up before dropping off your rental car.

Finally, if you do stay here, make an effort to go and look at the leaning tower - it's pretty awesome, and leans far more than you imagine.
