I stayd at the "A Better Stay" B&B in Rome for long weekend at the end of November and I can truly recommend it. Good value for money and the room was very clean (eventhough I was a bit nervous since I am very allergic to dust, but didn't have any problems what so ever, which shows the thoroughness of the cleaning) and it was great to have an option to cook something in the shared kitchen.
The owner recommended us to visit the local supermarket, which I would not ever thought of visiting otherwise and I bought lots of excellent hams and cheese which was then vacuum packaged so I can continue eating excellent local produce in London. And, all was much more cheap compared to the delis in central Rome.
Eventhough the location is not walking distance of all the sightseeing the tram is excellent and getting to the centrum is no hassle at all. The other good thing was that us arriving late was no problem for the hostess, they were waiting for us with friendly smile eventhough we arrived close to midnight.
If you go to Rome, consider staying in this great B&B, I'll definetely will go back.More
