The B&B is in a quiet, bland, but safe residential neighborhood close to the San Giovanni area. The B&B has six guest rooms, three on the first and three on the second floor (no lift). There's a floor below with a breakfast room (closed after breakfast) and a tiny little area by the computer that functions as a sort of "lobby" - but there's really no common area for guests. Each floor with rooms has two bathrooms: a full bathroom with a toilet, sink, and big bathtub and hand shower, and a second shower room with two showers and several sinks. I never waited long if at all for a bathroom, but only one of the three nights (Saturday) was the B&B full, the other two it was emptier and bathrooms were easy.
The B&B, in a private Villa within a secure gate, is located close to the Re di Roma stop on the Metro A line, only four stops from Termini; in any map you have of Rome, it would be in the lower right corner perhaps just off the map (beyond San Giovanni). Just do a Google Maps search for it. I was there without a car, walking and using public transit. The Metro ride from Termini to Re di Roma is very quick, 5 minutes tops, add extra time at busy times like rush hour. Walking to the B&B is fairly easy even dragging luggage - no impossible streets to cross, the walk to the B&B takes about 10 minutes (15 with luggage) from the Metro station. However, the Metro seems to shut down earlier than you would guess for a huge city; 21:45 on a Saturday night and the entrances to Re di Roma were closed. Fortunately, Rome has many buses and I soon learned that the #85 bus on Taranto runs often and til midnight every night and drops you right on Taranto, much closer to the B&B than the Metro stop. And the #85 takes you directly to the Colosseum and the Roman ruins all the way to Piazza Venezia, very handy. You may well buy a Roma Pass anyway which includes three days of public transit including unlimited buses and the Metro. You can also walk up to the Colosseum from the B&B in about 20 minutes - I did once and it wasn't a bad walk.
The B&B owners - mother and son - are very friendly and speak some English, enough to get by. They were receptive to questions and requests but I had none, really. I assume they live at the B&B - I saw them at various times of the day and evening.
My single room, #4 on the highest floor, was clean, quiet, comfortable. Room styling feels a bit old with dated styling but that's part of its charm. My room was long and narrow with a high ceiling and not huge, but compared to the two tiny hotel rooms in which I had previously stayed in Italy, it seemed large - plenty of room to spread out my luggage. My room had a single twin bed, a tiny wall-attached night table next to the bed, a single dining room-type chair, and a tall free-standing closet to put clothes in. There's one window you can open. There's also a ceiling fan but no air conditioning, so I'd be hesitant to stay here in the warmer months.
Breakfast is a pretty basic affair: some pastries, fruit, yogurt, snacks, and some cereal (hot milk; no cold milk - but I didn't ask for it). Breakfast is from about 7:30 to 8:30 but they'll ask you when you check in what time you want it. As mentioned above, the breakfast room is closed after breakfast.
Taranto is the main drag near the B&B. There's a supermarket on Taranto close to Via Pistoia, but as mentioned there's no real common area at the B&B, no place to prepare food. (Grocery stores are useful in Rome for other things such as buying cheap soft drinks, which are outrageously expensive at restaurants). Taranto also has a number of casual restaurants and pizza places along the way, some of them open past 8. I ate at the deli-type place at the corner of Aosta and Taranto, a place where you can get take-out Italian dishes, chicken, etc. plus there are tables for eating in. Good for very casual, cheap, quick, tourist-free dining; I would have eaten there again my last night there but they were closed on Monday night.
The B&B does have wireless internet (Alice) that you can use for free. Up in room #4 with my laptop, I found wireless would not come in reliably until I sat in the room chair with the laptop right up against the room door, then it worked fine (you can also sit out in the hall on a stool to get a perfect signal but not convenient if it's late and guests are sleeping). The B&B owners will give you a paper with a WPA passcode to get access. Note that to get the passcode to work, you need to remove the spaces from what is printed on the page and also type it in all small (lowercase) letters despite what's printed. I found my laptop extremely useful not just for checking email but for making cheap Skype phone calls home. The B&B does have a computer downstairs that they will let you use but there's a sign next to it suggesting they don't want you to use it long - I think it's THEIR computer too.
I'd definitely stay here again - I thought it was a good value for Rome. I booked via [--] .
