Bed And Breakfast Venice Italy

What is the name of a cheap, clean bed / breakfast for a stay in Rome, Italy?
Tell me when you left, and some tips for traveling in Rome and Florence, Venice and Pompeii.
I would not recommend a stay in BandB when i was in Rome in October of last year! – But what I would do is that if you find one you're interested in – Check it out first by google on the net and reading other peoples reports on it. I've heard good things about angeltode b and B – that is quick to respond to me, so unfortunately I went with another person – and were a complete failure! Also a great tip of Rome – the use of the meter – which is great and very cheap (1 Euro / trip) to buy their tickets in the machines or on the subway nearby cafes and bars – love it! It is very safe and well used by the Romans!
