Nothing much to add: very good hotel, too bad about the internet... We just went to the supermarket (2min walk), bought two Sim cards (we were two families, so it's a lot better than using roaming) for about 20Euros each. We had free calls and free internet access for a week...

Highly recommended as a long or short stay, easy to get to the center, close to the airport.

This four star hotel deserves its good ratings except for one item. 17 Euro ($25) charge for the internet. I have stayed in upper end hotels on every continent, and this is the highest charge for internet that I have ever encountered. Needless to say I just waited until I got to the free internet at my next hotel that was two stars. Now off my rant. I stayed in a two bed room for $120 Euro. The rooms are large for a European city, and the beds very comfortable. The hotel is very modern and clean and the hotel and rooms have a modern edgy style. Air conditioning is excellent, which can be a concern at even better hotels. They have a restaurant with a three course meal with wine and bottled water for 30 Euro. Very quiet except for noise from the room above. It is out of the tourist area so not congested. Staff efficient and business like and spoke English well. I would highly recommend the hotel for North American travelers.

We chose the AC Hotel cause it was really cheap and included breakfast as well as free drinks.
The room was small but very clean. The hotel is located near a main road about a 15-20min walk away from the city center. We took the bus to get there. The staff was nice but very professional and "cool" in a way that was a bit too much.
One day sightseeing in Pisa might be enough cause the city aint that big.

This hotel is more business than romance. It does not look very attractive from the outside but has a very efficient, nice and helpful front desk staff. Rooms are, again, in a modern style and some pieces of furniture reminded me of futuristic movies from 80’s. Bed was very confortable and a nice bonus were free cokes/waters in the mini bar and continental breakfast. Outside parking was free (pay for garage).
