We stayed for five nights in Principe B&B and it was excellent. As you can see on the map it's perfectly placed to explore Rome since "Roma Termini" - the main station - is just 3min. walk away. Like in most cities, this advantage is accompagnied by the fact that the district is probably not the most beautiful in Rome but by entering Principe B&B you'll forget about that.
The newly renovated rooms are well equipped (e.g. TV, safe), clean and comfortably quiet during the nights (there's no major road close by and I did not notice any noise from the main station). Breakfast was served between 8 and 10am and was even better than in some hotels. Victoria, the owner of Principe B&B, is very kind and tries to help whereever she can. For instance, when we arrived the first things we got were a bottle of cool water and a city map.

If I come back to Rome, I will certainly try to stay at Principe B&B again!

How much can be expected from the hostess at your B&B????? When we arrived to Rome, our luggage was lost by the airline and we were really anguished about it. When we arrived to the B&B, Victoria told us not to worry, to give her the information about our claim and that she would take care of it. She told us to go and enjoy the city while she called the airline, checked what happened and see that our bags were delivered to the B&B. AND SHE DID!!!!! The place is spotlessly clean, good size of rooms for Europe and location is quite well connected, but Victoria is an added value you won't find in any hotel, not even the Ritz, so please, trust me when I say she is amazing and will make your stay unique

Great hotel for the price we paid. Victoria is lovely and treats you like her own children - gives travel advice and prepares breakfast in the mornings. Our room was spacious and very clean, and the bathroom was small but spotless as well. Location is great for first-time travellers to Rome because you can find a bus from anywhere in the city that will take you back to the train station, which is a 5 minute walk.
For young couples, our bed was two singles pushed together, which we were not very happy about. Also, hot water had great pressure but did not last very long.
Overall, I would recommend this hotel for people who are worried about space, security (there were 3 sets of locks to get to our room), and cleanliness.

We stayed at the Principe B&B in early October 2007. Victoria was a wonderful hostess. Our room was small, but newly renovated with a king size bed. The bathroom was so clean it sparkled. There was a flat screen TV mounted on the wall and Internet connection in the room. The B&B is close to the train station and Metro and within walking distance of several sights. I will definitely stay here again when I return to Rome.
