Staff speak excellent English and are courteous and professional. The room was relatively small for two people (twin room) but clean, and I was disappointed that for a 4-star hotel room service didn't offer food in the evening (except coffee) and there was no tea/ coffee or ironing facilities either, and the on-demand TV/film services didn't work at all during our 3-day stay.
The hotel's about 10 mins walk from Termini station but not central to attractions, but a little walking never killed anyone, though literally around the corner was an adult cinema and a strip bar(!) but we never encountered any "undesirables" in the area, and there's an excellent homely family run restaurant a couple of minutes away.
All taken into consideration, I was a little disappointed with the stay there (for the price, and because it was touted as a 4-star hotel).
There's nothing inherently wrong with the place and addressing the points I mentioned and dropping it to 3 star and knocking 35 euros off per night would be more appropriate in my view.
I'd recommend the hotel, but with above reservations.

Not knowing Rome very well, we were a little wary of this neighborhood until we got there. We were pleasantly surprised to find that it's bustling during the day, quiet at night, with enough restaurants nearby to keep you happy, and some of Rome's finest museums within walking distance. The hotel keeps to the artdeco theme throughout, but with a decidedly modern touch - rooms lack no convenience, breakfast area is light and welcoming (with a good assortment f choices). The staff was a bit cool, but helpful when needed and certainly able to handle basic requests with ease. The restaurant is better than average and seems to draw a fare number of locals for lunch (always a good sign). If you're staying at the ArtDeco or just in the neighborhood, have dinner at La Famiglia (just a few blocks away) - fabulous antipasti table, friendly service, and marvelous pastas!

A gem of a hotel. Convenient location - walking distance from Termini Train Station & also a metro stop. I've read that the area can be seedy, but I thought it was fine. I never heard any noise & I never saw any "bad types". In fact, there are consulates around the hotel area & there are soldiers placed on most street corners, creating a feeling of safety. The room was moderate size (maybe a bit tight for a couple, but I could have had a single size room, not double.....not sure), neat, modern, comfortable, clean & quiet. Windows were double glazed. Air con worked well. Staff were always very friendly & helpful. Breakfast was typical of european hotels - simple but plentiful. Free computer access in lobby. Hotel allowed me to check in early at about 8:30am. Highly recommended.

The hotel is within walking distance of the termini which makes it handy to get around and you are also close to metro stops but it you want to be in the heart of the action you might find the hotel a bit remote.

The hotel is clean and the staff were helpful and friendly.

The rooms were also clean and comfortable but a little on the small side. We booked a room with a spa bath which was lovely after walking miles seeing the sites!

Breakfast is standard continental fare and you can help yourself. Normal selection of pastries, muffins, cereal, meats, cheeses etc..

We ate in the hotel restaurant on night which was very plesent and perfectly acceptable if you've had a long day and can't face going out.

Some people have commented on the area being a little 'seedy'. Yes there is an adult cinema and strip bar in the next street but being in mind we walked past the strip club 3 times before even noticing it was there it is certainly not a seedy as people have made out.

The hotel was a bit on the pricey side for what you got but that seems to be par for the course in Rome.

On the whole a good hotel that I would have no objections staying in again.
