Overall, a very good stay. Convenient location (500 meters from termini) and well situated for many destinations. Very comfortable room: excellent AC, nice fridge, lots of space. A few small issues: there is essentially no on-site staff. This means several things: 1. The guests check themselves in. Remember to bring the entry code that is emailed to you. Months had passed from when I booked until I arrived and I forgot the email. A reminder sign at the front door would help. 2. There are some modest cleanliness issues. The bathroom cup in my room was dirty and moldy. It should have been discarded. 3. The telephone rings into the front desk which is not staffed (I could hear it ringing as I tried to get in the front door). It would be better if management forwarded these calls to their cell phones if they choose not to be on site. 4. And fundamentally, if you require on-site service, this isn't the place for you.
Next time in Rome, I would stay here again as I now know the idiosyncracies of this property.
