Dandi Domus is an easy to find place. You can start from here your daily walking tours through Rome, the Colosseum is within 15 mins. Even the metro can be reached in 5 mins. Three shops are next to the gate, so you can buy what you want everytime.
There is a fridge, a caffee maker and a water boiler in the room where the three of us could easily fit in.
Nice staff, the rooms were cleaned everyday.
