Gianluca's BnB is very nice. He has 4 well appointed rooms with private baths that are modern. My wife and I went with 3 other couples and Gianluca's place accommodated us all. We all felt very comfortable and enjoyed our stay. Gianluca is very friendly and available. He provided his personal number if there were any issues.
His BnB is well within walking distance to the major sites in Rome. He is about 5-10 minutes from the train station. Our group walked mostly to all of the sites with were in 15-20 minutes from the BnB. The Metro is only a few blocks away, so easy access to getting around Rome.
Gianluca provided suggestions of good restaurants (one we enjoyed so much we went twice), great gelato, and sites to see.
I would highly recommend Gianluca to anyone that is looking to stay in Rome.
Because of the size of our group (we were taking all of his rooms), he provided a discount to be given to us when we got there. When we arrived, it was the first thing he brought up. I find him very ethical, honest and friendly.
