Well, let us start with the positive things:
Excellent location, just across the gate of Rome termini station.
Good price.
24 hours reception.
I guess it is good value for money.
The negative things:
A few additions, which are not costly can help in making life easier for the clients.
A few hangers for reusing the towels is cheap and will save unnecessary use of extra towels. We had to hang the towels over door handles.
A curtain to protect the bathtub will make life easier for the house keepers when making up the rooms, and it is not costly.
Also a dispenser for shower gel and shampoo is much better than the present items.
They give you the room key in a quite heavy metal chain which you handle to the front disk whenever you go out, it is better and easier to return the keys just at check out and keep with you (conveniently) all through your stay.
Anyway, those may be some areas for improvement which are not costly.
Overall, nice hotel, good value for money. I would stay again.
