The apartment is very nice, and close to city center and Colloseum. Very good for 4 people and good pricing.
I would recommend for tourists.
However the host was very preoccupied with collection of a "special tax for tourists" 3€ per night per person and it was a surprise for me because I didn't know about it untill I already booked the apartment. I paid but I don't think it was legal, so I would advise others not to pay this "special tax" as there is no way any host can make you pay this.
