We only had a one night stay at Naden's place, but it was perfect for our needs. Just a short walk to both Roma Termini Station and to the Colosseum, and easy to get to other major attractions either on foot or by nearby public transport.
Naden was very quick to answer us whenever we asked him a question, and upon check-in he gave us lots of tips on what to do and see, and how to quickly get around the city.
Overall, we found Naden's place an excellent value and would highly recommend it as a base for a visit to Rome.
