I found Casa Aurora through previous reviews on TripAdvisor. I had to go to Genoa for work and needed somewhere inexpensive to stay. As my budget wasn't big, I decided I would much prefer to stay in a B&B than a grotty cheap hotel in a seedy area. So I settled on Casa Aurora as it was very reasonably priced (50 euros a night) and very well located.
It was everything I could have hoped for and more. The owner (I forget her name, but a lovely lady!) was so kind and friendly, and made me feel completely welcome in her lovely home. The B&B area is separated from her family's residence, so I didn't have the feeling of being in the way, which you sometimes get in a B&B run from someone's house. My room was clean, charming and very homely. She laid out a lovely breakfast for me each day, and helpfully provided tips and information to make my stay easier.
I would not hesitate to go back there if I find myself in Genoa again. I have recommended it to various people who have gone to the city since, and they have all been very satisfied. The only downside is the mammoth staircase, but actually having that invigorating bit of exercise every day made me feel better about devouring the lovely breakfast at Casa Aurora.
