Pleasant B&B run by a nice family on the northern outskirts of Rome. Staying at the Villa Rome offers an interesting glimpse of living in suburban Rome. Rooms are all detached from each other and they reminded me somewhat of in-law apartments. Very pleasant large common area that serves as the breakfast room and also includes a kitchen where one can prepare their own meal if desired. House grounds are well-kept and there is a pool that guests can use. Would be nice to relax outside on a summer evening but the mid-March weather was not conducive to a swim! Getting to the city is not an issue but one would probably only want to make the trip once per day. Villa Rome is perhaps a two minute walk from the Ottavia Station on the FM3 suburban train line which takes you direct to the Vatican (San Pietro), connects with the Metro (Valle Aurelia) or directly to to the Trastevere neighborhood of Rome. Trains are frequent throughout the day, roughly every fifteen minutes until after the evening rush hour. The 907 bus is probably a better option for returning in the evening after 9:00, It leaves from the Cipro Metro station and stops on Via Trionfale in front of the Ottavia train station. There is also an overnight bus (N6) that plies a similar route. A very enjoyable stay with the only negative being that the WiFi signal needs to be stronger (probably needs a router added in the breakfast room).

Admittedly, the hotel is quite outside from the center of Rome and must be a pain to get there by taxi and busses, as the latter are indeed not very reliable. However, there is a train station very close to the hotel, via which it's very simple and cheap to get to the center.
The price of the triple room was very reasonable and actually lower than expected. The breakfast room as well as a little kitchen was accessible 24/7. So you could always have a tea during the day. The breakfast itself wasn't of high quality, e.g. there wasn't any sausage (but that's just the German in me speaking;), but satisfactory.
The atmosphere was nice and the family/staff very helpful and pleasant. Basic conversation in English was absolutely possible.
If you plan to spend most of the time downtown of Rome and not have to go back to the hotel several times during the day, Villa Rome is a very good option to consider.

The house is located at a distance of one minute walk from the railroad-metropolitan station Ottavia, and it is quiet because is protected from the street noise with a brick wall. There is an open water pool for guests.
The food was much better than I had at other B&B places, it included a big variety of ripe fruits - it was November; the guests are allowed to use the kitchen with a gas stove, many pans, dishes, spices, cooking oil.
The hosts were very friendly, were always ready to help, even they made phone calls because I do not speak Italian. They even allowed to use their computer to check and send E-mail. Later I discovered that across the street from their house you can use Internet, telephone and even Skype at a very low price of less than a euro for half an hour - the cheapest service that I found in Rome, and I did not find Skype available at other places.

Villa Rome is a very nice big house with nice little rooms including bathrooms, a wide and friendly room for a tasty and big brekfast with a big kitchen, where you can prepare your own meal. outside there is a swimming pool where you can cool down and relax. The owners Isabella and Paolo are very nice and friendly people who help you out with information if necessary and keep the place clean. The house is in a calm area and easily reached by train and later at night by night bus. I love this house and their owners very much so I will visit Villa Rome for the third time this year
