I had a perfect stay at Nancy's room. Nancy is a great host in a good temper and very helpful. The room itself is as described, clean. Anyway it's really quite in the night. Nancy's balcony is beautiful for having a coffee in the morning.
The location close to Termini station is a good starting point for tours to all places in Rome.
I really can recommend a stay at Nancy's place and hope to be able to come back someday.
