He is the "best" host in Rome, I think.
First of all, our plain arrived quite late at night but he waited for us until we arrived at his place, which seems to be flexible. (But I told him that our plain is going to be late in advance).
Second, his place was very clean. It was really comfortable for us to sleep in the bed, and he always cleans the hallway, kitchen, rooms of corse, and bath rooms etc...everywhere in his apartment.
Third...I can tell you his good points more than 10, but I think it's enough for you to decide whether to stay here or not
Oh, and it is very convenient for you in terms of location, which is within around 15 minutes on foot from the Rome terminal station to there. And you can go to the Colosseum within 10 minutes on foot as well. Of course you can take the public transportation too, which is less than that.
So...to sum up, he has a great hospitality, even though I, a Japanese, make a judgement.
Thank you again Rene.
Ciao.
