I didn't used to write reviews, but with this hotel I was really disappointed. I'm traveling quite a lot and have some comparison with other hotels and especially as I spent a night before also in Rome but in the center (Starhotel Metropole) I can even compare two 4 star hotels.
So... on the pictures hotel looks pretty well, unfortunately as soon as I arrived there spotted that not everything is really new, but that wasn't any problem.
The real problem was that I asked for non-smoking room but unfortunately there was not very nice smell in the room. It was not only smell of smoking but also kind of smell as you would have a multi-day party in the room and forgot to not spill a wine around. Or something like that - at least that wasn't nice smell.
I tried to get rid of it by opening the window and leaving it for the whole evening as went out for a dinner.
Another point is that I couldn't have a dinner in the hotel restaurant as they booked it for something else. I had two options, go back to the center (ca. 30mins by subway) or go by walking to nearest restaurant "Taverna dei Porta" or something like that, close to obelisk. That restaurant was really good and can be used for romantic evenings. They do serve very good food - I tried their so called Grilled mix, which was big plate of different grilled meat.

Returning to the hotel - they aspire to be 4 star hotel but as for me it was not more than 3 European stars. Room was quite small, even if it was double bed, there were just two beds connected which is not the same as double bed. I can easily say that it was the size of small London hotel's rooms.
Next morning I couldn't have breakfast in the main restaurant and was moved to smaller back room. This time it was because they decided to serve different food to normal guests than to organized group of probably Spanish tourists. Unfortunately "normal" guests meant worse food, just basic stuff like white cheese, joghurt, milk, sweet cake and nothing else besides coffee (good) and juice (it was more like an orange drink or maybe nectar than a real juice). I didn't see any other guests besides organized group.

Moreover I asked for a room where I can sleep till 9-10 without unnecessary noise and guess what... they put me on the side facing to huge development side, so starting from ca. 7:00 - 7:30 I couldn't sleep, whilst on other side looked much more calm.

I had very same experience with breakfast on the second morning.

At the end of check-out I was asked again to pay for second night, whilst it was already paid at booking time directly to the hotel. If I wouldn't state couple of time that I already paid for both nights they would happily charge me again. I better don't want to imaging if it could be sorted out with them and how much time it would take.

To summarize - don't go there even if you need to be in EUR district in the morning as I had to. It's better to stay in the center in well known hotel like Starhotel Metropol or any other as you can find probably even better deal than this [--] hotel.
