Superhost doesn't do Max Justice. He is very friendly, helpful, knowledgeable and has a passion for Rome, its culture and history that he willingly shares with you. Max works in the tourist industry so his recommendations are invaluable.
The space is very comfortable and clean, the pictures show it correctly but it is nicer than they portray.
It is located out of the touristy centre, but not too far at all in a nice local neighborhood (no concerns with safety or anything like that).
Everything is easily accessible by the buses which run regularly to the city centre, the Vatican the metro etc. It is walkable from the city, but be warned there is a rather large hill involved (nothing impossible, I did it several times). Just down the hill, a much easier walk, is Trastevere a popular district for restaurants.
Don't hesitate to book here as it is an excellent place to base yourself for a few days or more exploring Rome.
