we stayed at superior room. the guy over there is great. he always tried to help us about places, and directions. You can ask anything to him and be sure that he will give the right answer. The bed is okay but the breakfast could be better. Also there is no place to eat so they serve the breakfast to the room.

Mr Johnny was gracious enough. His Italian/English is nearly passable; but, his kindness makes up for it.
The room was spacious and grand. However, upon closer inspection, a little maintenance would elevate this dump from falling-apart to rather charming and quaint. Its appearance (and, location) ought to be "elegance"...however, it is in need of repair and attention. Dirty light switches; missing bulbs in lamps; "disco-fridgette" (light in fridge was a constant blink); bathroom light fixture was hanging from wires and caused one of the only bright bulbs in the whole room to "twitch"; drawer on armoire broken of hinges; keys to wardrobe falling out and off; a/c was good(!); shower was crazy and dirty.
For us, it was an adventure. However, I cannot recommend it in its current state. It has incredible potential if only the owners would recognize it.

We paid Euros 160 per night from bookings.com for this place. It was WAY OVER PRICED for the rooms we got. We stayed 3 nights at this B&B. It's a stone's throw away from the Barberini subway station, but it's an uphill walk - not very good if you have lots of luggage. We had emailed the B&B asking for directions a couple of days prior to arrival but there was no response. Nonetheless we managed to find out way there. They have an indian man (from Chennai) manning the reception on the days were were there, so not much help regarding local knowledge and recommendation. Rooms were big, but noisy as the rooms we had had windows facing a main road and a club down the road. Breakfast was extremely disappointing expecially for the price we paid - croissant came in a bag. We paid less for rooms in Venice and Florence and we had fresh bread and croissants daily! Hot water was very inconsistent - you get it hot then cold then hot then cold without having to adjust the tempreature. Rooms look nothing like in the picture.

While the host is very gracious and the B&B location is pretty good, we had some issues with the condition of the room. Our sheets had a blood stain on them, the towels were very small (not much larger than a hand towel), the toilet was constantly running, and the door creaked VERY loudly. We also had an issue in checking in. The host knew what time we were arriving, so I expected no issue in checking in. However, when we arrived, there was no answer at the front gate or door. No one answered the phone. Another guest of the B&B happened to come out and had a different telephone number. Ended up waiting one hour for someone to show up. Breakfast is so-so and is delivered to your room.
Not really a good value, and I would look to stay elsewhere before returning to Commodus.
