Nice hotel close to the train station.
A very nice hotel. Friendly staff, good access to transportation. To reach if from the Termini, take the Metro train to the Flaminio station, then change trains and take the train to the Euclide station. From there it's a couple of block walk to the Duke.
Rooms are nice, the bath in the more expensive rooms is amazing! Room prices varied from affordable to expensive based on the room and the night.
They offer a shuttle service to Flaminio, but it's just as easy to take the train.
Would stay again.
