We are so glad we stayed with Marlene! You could walk out the door and see the colosseum one block away so it was incredibly easy to get everywhere. We walked to the Vatican and the historical center daily, but there is also a subway stop right next to the colosseum. Marlene was an amazing host and had snacks and water out for us and helped us find amazing places to eat! Room was clean and the bathroom had good hot water. And good reliable wifi throughout our stay which was a godsend after all the issues we had before!
