Before I found out I was going to have an additional traveller on my trip, I had originally reserved a spot in the hostel portion of Hotel/Hostel des Artistes, which runs Carlito's Way. We ended up reserving a private double with shared bath, which at the time was significantly cheaper than the private ensuite. Upon arrival to a dark and rainy Rome, we made our way to Hotel des Artistes to check in (the check in/lobby area is on the fifth floor). During the check in process we offered a room with private ensuite bath for a discounted price for the second night of our stay, which we are glad we did. After checking in, we were led a couple blocks north to an annex which was located in one of the three buildings that house the Hotel des Artiste/Carlito's Way rooms. The room was sufficient, nothing luxurious, but it provided a place to sleep and the shared bath was directly across the hall and was usually never occupied which was nice.
During the day after our first night, our bags were moved by the staff to our new room in a building next to the main building and we found the new accomodations much more luxurious. A flat screen tv mounted on the wall at the foot of the bed, a spotlessly clean bathroom, and efficient air conditioner were welcomed.
The use of three buildings keeps the exact location of your room a secret until you arrive, but they are all within a few minutes walk of the main building. Each building has a lift, which makes lugging heavy bags much easier. The main building is a few blocks from Rome's Termini train station and metro, which makes travelling much more convenient, although Rome is better explored on foot. The staff were very welcoming and went out of their way to help us feel comfortable. Overall, the private ensuite rooms of Carlito's Way are Highly Recommended. However, if your main concern is your budget, the rooms with shared bath will serve you well as a base for showering and sleeping.
