Daniels place is pretty decent. We liked our room it was very spacious and with plenty of storage. There was a comfy couch inside the room to relax. The bed was nicely made with a surprise box of chocolates. :)
There is a common area with a well equipped kitchen and free breakfast/coffee. There are plenty of maps, guides, books and practically any information you might want on Rome.
The only negatives were the cleanliness of the bathroom, particularly the shower area. The location is bit far from the centre but there's a bus right outside. Too give you a rough idea it took us about 40 minutes to the Vatican and 25 minutes to the Colosseum.
Even though we only briefly met Daniel, he was lovely and answered any questions.
Overall, the place is definitely worth the good price but it is more like a guesthouse/hostel then Airbnb.
