The room was exactly as expected based on the description Carmen provided. It's small but perfectly sufficient for a brief stay. It was clean, and towels, extra bedding, some kitchen supplies, and city maps were provided which is great. The only complaint really would be that if you like a cooler room temperature the fan isn't enough. We did not get to meet Carmen personally but she arranged for the owner of the B&B in her building to check-us in and he was very nice and helpful. Check in/out is flexible, and we were able to keep our luggage in the locked apartment on our last day before leaving the city. The neighborhood itself isn't great, but it is very convenient - close to the train station/metro and walking distance to the Colosseum.
