Simone & Susanna's place is excellent for holidays. I spent - along with four more people - 6 nights at the apartment. The apartment is comfortable, well decorated, and has some amenities which are not so common to find in B&Bs (e.g., tv which allows you to access your netflix account). I stayed in the apartment on the new years' eve and had a privileged view of the fireworks from the terrace. The apartment is surrounded by balconies, which I'm sure makes it is even more lovely in the summer when you can have breakfast or a glass of wine outside. Location is also privileged. There is a metro station next door connecting the apartment to Rome's major attractions in a few minutes. On top of that, there is an award-winning gelateria right in front of the building (it is worth going there even during winter! In fact, it's worth going to Rome just for that gelato!) and many good restaurants nearby.
Thanks Simone & Susanna for being such great hosts!
