Just finished a trip to Rome and we stayed at the Hotel Cosmopolita in a double standard room. Overall, it's a great choice and in a great location, if you want to be close to the old city. Only complaints: the room was a little small, but worst the shower was extremely small. If you are a large person (over 200 lbs), you may have problem getting in/out and turning around. It's smaller than a cruise ship. Other complaint is 12 euros (per 24 hours) to use the internet from you room.

Beside these points, we enjoyed our stayed and the hotel. Staff is very good; breakfast is excellent, rooftop terrace is nice, bed was very comfortable, maid service is very good, a/c is very quiet.

The hotel is in a great location, 10-15 minute walk to the Colosseum. The only downside to the location is it is 10-15 minute walk to the nearest subway station (Colosseum or Via Cavor). Service was excellent, room was big enough, shower was small but that seems to be normal based on what I've read. The hotel has a bar inside and a restaurant (The Glass) upstairs where the free breakfast is. Surprisingly, The Glass is an amazing restaurant and definitely worth at least one dinner (we ate there two out of six nights).

This is a really nice hotel with a really good location. It's very centrally located and most sites in the city center and easily walkable. The breakfast was very nice and got us a good start

Comfortable 4* hotel with a great location one minute stroll from the historical sights of the Via dei Fore Imperiali and the spectacular view down to the Coloseum. Would recommend upgrade to a Superior room in order to take advantage of a larger room size. Spotlessly clean throughout with a modern bar area - The Glass Bar, used by locals and guests alike, offering good value for money buffet including drink for just 10 Euros. Lift available to all floors but still a few steps to navigate. Overlooks busy road but double glazed windows keep most noise out guaranteeing a good nights sleep after a hard days sightseeing. Air conditioned and daily maid service. Buffet breakfast in the Glass restaurant on the mezzanine level provides a good choice to start the day.
All the sights of Rome are walkable from here, 5 minutes to the Trevi Fountain,10 minute stroll to the Colosseum, 25 minutes to the Vatican.
