The location of the Porta Maggiore (an ancient, touristically unspoiled and well preserved city gate) is ok - public transportation is readily available from the front door (trams #3, #5, #14 and #19 stop right in front of it).  And the price is right.

Get a room at the back of the hotels in the area, on one of the upper floors unless you are there on a Saturday night.  On Saturday night there is a very noisy disco out back that blasts you out of bed until 5:00 am.  Out front is a lot of traffic noise.

Do your own research for sightseeing before getting there.
