My son and I really enjoyed our stay at Nori Guest House. It is in a wonderful location (quite close to the Colosseum) and we walked everywhere whilst in Rome. The facilities are spotless and the rooms are very spacious.
Unfortunately, we didn't have access to the kitchen at all during our stay, and it would have been nice to be able to cook some of our meals, or at least be able to make a cup of tea or coffee, as we spent six nights there. However, apart from that minor disappointment, we found Nori Guest House to be superb.
