We booked the 207 Comfort Inn because of the overwhelmingly positive feedback on tripadvisor. We did not care much about the comparably high price (150 Euro/night) since we thought to have found a gem in Rome which is worth the money… no chance. We left the “hotel” after 5 days although we had to pay for the full ten days of our planned stay - and that’s why we left: We really need a quiet room for the night after a buzzling day out in Rome and the Comfort Inn claimed to have “soundproof” windows. Rubbish! They have simple thermo-isolated windows with almost no sound-blocking function and all rooms go to the main street so you have no alternative. The Via J. Cesare is a very frequented street with a permanent street market so you might expect to be “soundproofed” until midnight at least. Do not be disappointed anyway: If it’s not the street noise that keeps you awake, it’s the underground that goes right under the building. The metro ends at midnight and starts again at 5 am. But do not expect to have 5 hours of continuous sleep. There are eight or so waste containers just in front of the “hotel” and garbage collection is every night at 3 am for half an hour. Believe it or not they really come every night (at least during the five nights we spent). This is for the noise but it is not the end of our complaints list. One evening we had no warm water because the boiler was down. They do not serve their own breakfast but you get a voucher for a cup of coffee and one piece of pastry at a neighbouring bar – if you get it. Only at one out of five mornings there was a person at the reception desk. No voucher no breakfast. Good strategy to save money. At least the bar is very good and not too expensive. There were a lot of smaller annoyances such as: new towels only every second day (do not expect that they are dry the next day), no depositing opportunity in the bathroom, tiny TV with only one English channel (BBC world which drops out during rain), no telephone, small beds, very restricted English skills of the staff (although they try to be helpfull) etc..
Altogether we spend a holiday we will never forget. If this is what you are looking for. Go ahead!

very close to metro Ottaviano, which in big sightseeing cities is one of the most important things, is close to several restaurants frequented by the locals, also close to quick, good, food, ATM's, Vatican City. Felt safe. was clean, staff was nice, most spoke no English, but they attempted, so we were able to communicate.
internet was advertised but it was spotty. sometimes didnt work, or if we sat near door, it would work.

Rooms were quite small but VERY clean. Receptionist polite and helpful. Centrally situated and very easy access to the whole city. A little expensive in comparison to its 4* competitors.
Contrary to comments on here the rooms do have safes inside the wardrobe.

Not sure about breakfast but was unable to get coffee at anytime. Also no tea/coffee making facilities in the rooms.

Out of the hotel and 1st right is a restaurant called la caravella,, food was excellent and service good ,value for money ok. Another restaurant in the next street was L Isola Della Pizza. 80 euros for 2 but very very busy and good quality food. Not many tourists in there but was full, (a good sign)

I would just like to warn people before they book this establishment BUT I NEVER DID STAY THERE. I booked my stay months in advance with a credit card. No one contacted me to let me know that it had expired until 2 months later. I was given 48 hours to contact them. I did so in an hour; however, they decided to virtually double the overall stay. I think this is disgusting and I would just like to recommend that you do not stay there.
