great location, within walking distance to trevi fountain, Spanish steps, pantheon on one side, and coliseum, forum and palatine hill on the other. lots of restaurants and bars nearby and good shopping. there is a Coop grocery close by so you can buy supplies there to cook or make sandwiches and there is a convenience store opposite.
Very clean and comfortable. However i would not recommend for more than 3 persons.
Only downside i had was that the smoke alarm in the kitchen goes off easily, but all-in-all I highly recommend this place.
