Wi-fi is free and reliable. Staff were very friendly. 11am checkout. Room is as nice or nicer than Hotel Julia, and pretty much the same thing but without the noise and 40e cheaper. Only stayed 1 night but should have stayed all 4!

Probably depends on which room you get though, as I can see how some of them would be noisy, as the front of the building is on Via Cavour. But my room was at the back and fine.
Location is awesome, close to Roma Termini and Colosseum etc. Double bed room was 65e (single use). Breakfast was a bit lacking, but not complaining for the price.

We did not enjoy our stay at Hotel Cavour and we found the area surrounding Termini station to be an undesirable and inconvenient place to stay in Rome. Even if you’re used to walking all the time, it is still a good 30+ minute walk to the nearest sites. A better area would be around the Spagna subway station. Aside from the location, the hotel was just not very nice. The hallways smelled terrible and the room didn’t smell very good either and was very hot (in early March). And when we tried to open our window to let the smell/heat out, the stench from the Chinese restaurant in the alley wafted in—so you had to make a calculated decision regarding which smell was worse. There was seemingly zero ventilation in the bathroom, which was probably no larger than a 10-foot closet. The lighting was bad, the walls were painted an odd yellow-y color that made it feel dirty, and the air conditioner/fan did not work. Breakfast was bread and off-brand Nutella and juice. I believe we paid ~$88/night for the room, and it was not worth it—I’m not even sure that we would have stayed there for $50/night.

What do you want from a city-centre hotel in a major European capital? We look for a good location, clean room with good/clean bathroom, fair price and good staff/service. This hotel ticks all the boxes.
Room - small but perfectly functional, spotlessly clean bed/linen/towels. Quiet too.
Staff - helpful and charming. I would rate this hotel for the hospitality.
Location - as stated by other reviewers, it really is ideal - centrally situated with brilliant transport links.
If you don't need plush indulgence in your hotel room to make your stay in Rome memorable, but instead look for a good value, safe, clean, warm & welcoming place to rest & refresh then you could do worse than stay here. We will stay again.

I stayed 7 nights in a single room at Hotel Cavour. The location of the Hotel is excellent. It is only 150-200 m. to Rome's main railway, metro and bus station Termini and a few blocs away from the Cavour Station. Transportation within Rome and to other cities of Italy is not a big problem. A bus-stop just in front of the building entance and many taxis around. Plenty of restaurants, cafes, pharmacies, souvenir shops and boutiques available in the near vicinity. In general the area was safe even at night.
The room was small but very functional. If you like to stay in a hotel and spend the day and night there, this is not the right address. But if you prefer to use the hotel as a fresh starting point to the day with a breakfast and for having a shower and a good sleep after a backbreaking day, that is. Of course the breakfast is an "Italian breakfast"... coffee, croissant, a slice of bread and jam. The room was CLEAN. The bath towels changed everyday and were so white looked like new. A small shower but a high water pressure making you a relaxing massage. A working air condition included in the price ( which is not usual in most Roma hotels. They charge you extra.) Although the hotel is situated on a busy road there were no disturbing noise in my room.
An excellent team in the reception. All were very polite and helpful. Alfredo, Lorenzo, Andy and Elisa replied my endless questions with patience.
If you compare the price you pay and the services you get it is absolutely a value for money hotel.
