We always stay at the: Hotel delle Nazioni Rome.

http://www.hotel-dellenazioni-rome.com

It is directly behind,and to the left of the Trevi Fountain....Wonderful to be able to see the Fountain without crowds.

You can walk everywhere from here(maybe not to the Forum,unless you are a true walker) and the restaurants are numerous.
We loved having diner in front of the Parthenon a lot of the nights we spent there.

Italy is my favorite country in Europe and cant wait to get back to Tuscany again soon.

Have a wonderful time!

Cheers

Pat and Ray
