Me and my girlfriend stayed in Rome for 4 day, first we book 2 days and then 2 more. We didn't stay a lot in the room, but it was pretty big, clean and nice, location is a bit out of the center, but close to almost every possible public transport in Rome and only 20 minutes walk from Colosseum and the Forum (for all the rest is probably better to use public transport)
But the best part of the apartment is Sergio! He was super nice and helpful, give us a lot of tips about Rome and answers every question we got almost in every hour, he even helped us to plan a trip out of Rome and kept our luggage while we was out of the city!
I believe it's a great value for money, especially with host like Sergio!
