I stayed at this apartment this August for 9 days, I personnally can say without reservation we had a very good experience with our apartment 215 we stayed 9 nights Danielo is the owner was communacative very hospitable and from day one told us what to see what was good what was bad on a map just as well as he recommended a few places that we hadnt planned on and were gems like Viareggioand gave us details of a very good bistro called Brunos in Pisa. I must thank him for warning us about the ZTL zone which is a restricted car zone and if you enter can cost you 180 bucks didnt know of it be warned .
I saw some people make comment on the music some nights yes if you stay at the back Wed and I think Saturday and Sundays you can hear music late night I felt it sounded loud because it such a quiet place and it does add to the character of the area most Cities you would have blaring people cars etc as we didnt spend too much time there and were exhaussted it only bothered us the first night .
Very easy to get around the autostrada and Pisa are about 5 minutes away
The aircon was fantastic the showers hot.

The rooms were clean decor and furniture is a bit dated for UK tastes and the sofabed a bit uncomfortable to sit on,however I still feel it was excellent value for money and have recommended to all my friends already if you want 5 star comforts this isnt for you however for us mortals on a budget and with kids you will benefit from value for money.
I am already planning to go stay again ....
Lastly do not expect this place to be the Hilton its not its affordable and you have to compromise
if driving take Sat nav like Tom Tom with you it will make it so easy for you.

Theres a good cafe and bank within feet I guess I would recommend that you try get an apartment to the front of the building if you dont want the music as stated above.
Internet was charged resonably by hours we paid €10 for 7 hours
all issues were dealt with promptly by the owners
