Good things: big and clean room, breakfast included, location is good for sight seeing with metro station nearby and Colosseum within walking distance. Many restaurants and shops around.
Not so good: we cannot use the kitchen by ourselves (sometimes we want to cook noodles), no hair-drier (i dont see any in my room or in bathroom), late check in extra cost (although it was informed earlier but we still think its not so good, i have never been charged this kind of fee before though i also had many late check in for airBnB bookings), early check out time (10am, to us its not a big issue since we normally go out from morning till late evening and the host is kind enough allowing us put our luggages there)
Overall, we had pleasant stay at Nori B&B.
