Hi, When we are in Rome, we always stay at:www.hotel-dellenazioni-rome.com
It is a "boutique" type European hotel directly behind Trevi Foutain.It"s rates are about 250 Euros per night and includes a great breakfast.It is within walking distance of everything almost(Colluseum is a longer walk). We used the ships transfer(we paid for it) to their post-cruise hotel and took a taxi to our hotel.It was only 4 minutes away.I booked through
www.venere.com in Italy. Hope this helps a bit,"Ciao"
