We are a family of 4 (2 teens) and we were visiting Rome for the week immediately before Christmas, returning home on Christmas Eve. Hotels with rooms that would sleep 4 were pretty expensive and hard to find and an apartment which gave everyone more space seemed the perfect idea.

Found these apartments on the internet and emailed for information. The responses were timely and written in good English, very welcoming. First thing to know is that there are two addresses and certainly the one we stayed at is not a b&b, it is a self catered apartment. We wanted to be near the Forum and the Colosseum and so we picked the location at 92 Via Baccina. It was literally 5 minutes walk to the Forum and the Colosseum and you could see the Forum from the apartment windows.
There was nothing to pay in advance and we were advised that we would pay in full on arrival - in cash. The owner is a pilot and he lives in the top floor of the building.
Via Baccina is a very quiet street, almost no traffic at all and yet there are great restaurants within a couple of minutes walk and the nearest metro stops ie Cavour or Colosseo are within minutes. Last year when only two of us visited we stayed at the Inn at the Roman Forum (wonderfully luxurious) which is about 50 yards away from the apartment, so its a good area.
Our flat was on the first floor and consisted of a large living/dining room, one twin and one king bedroom, a bathroom and a very tiny kitchen. The kichen is just about big enough for one person but it is perfectly adequate for what we needed ie coffee, tea etc. Having said that it had a large fridge/freezer, a washing machine and a dishwasher so was quite well equipped.
The furnishings are simple but antique and charming - quirky. I was worried that the apartment might be draughty and cold but the heating and hot water worked really well and we were thoroughly toasty throughout. There are free internet based phone calls to a lot of international locations as well as local (USA and UK for instance).
Some of the bathroom fitments need updating, there's some ants that need looking at in the kitchen but the bed was very comfortable, the sheets and pillows were good and we were very happy there. The location was so good. We could be at the Colosseum within about 7 minutes and the Trevi Fountain in about 10 and for such a great location it was just so incredibly quiet at night. We walked just about everywhere except the Villa Borghese and the Vatican.
There are a couple of little food shops close by, restaurants, excellent coffee shops and gelateria. Would definitely stay here again. We paid 870 euro for the week which seemed a good deal against what we would have paid in a hotel for 4 of us. If you want plush or fancy, this apartment wouldn't suit you. If you want a charming Roman experience in a fantastic location then have a look at it.

La Dolce Vita B&B is very centrally located around the corner from the Trevi Fountain. It is quite large and being that there were six of us, two bathrooms and three bedrooms were wonderful! The flat was clean and comfortable; the kitchen small but it worked out fine. Mario is more than gracious and very accommodating. We had a problem with the washing machine and after telephoning during a holiday weekend, Mario was there the next evening. He made sure everything was in working condition for us. I would absolutely stay there again.

Stayed for 5 night during week stay in Tuscany for a wedding.
Not the easiest to find if driving about Lucca by car through the narrow street swith shoppers on your first day!!!!!!

Up a tenemanet 1st floor next to a lovely cafe, good prices/food.
Coupld on top floor phoned owners to gain access as we missed msg on front entrance door as it was open.

Only problem was expecting towels/linen to be changed on 4th day, really needed fresh towels, but it didn't happen. Would have got them if i phoned owner probably though

Little cafe downstairs is excellent, friendly owner, good food and prices.

Would visit again if onbudget....

This suite was perfect for our family of 7. Traveling with 3 children and 2 seniors is not easy and this apartment and its owners are wonderful. The simple yet comfortable accommodations made our time in Rome feel like we were at home. 3/2 apartment in Rome in such a neat neighborhood was perfect for our family. Only a 5 minute walk to Trevi fountain, grocery store, and restaurants. Affordable and comfortable for large groups.The owners (Luca and Mario) are helpful and so pleasant to deal with also, they even arranged for a driver to take us straight to the apartment after a long trip! Enjoy Rome but use caution while sightseeing, pickpockets galore.
