Laura was very kind and nice. She let me know all the 'must-visit' places in Rome and it was really helpful!
Before I arrive, she answered me for every questions I asked her. She told me to come to the second floor. However there is another bnb on the second floor as well. Her flat has a sign 'Vacanze Romane', so be careful about that. (I went to the wrong place at first :-/)
Although she was a nice host and the room was quite close to the city center, there was one thing I couldn't satisfy with. My room smelled like a bathroom. Even the hallway smelled like a bathroom. I didn't know where the smell was coming from.
On the first day, I kept the window open while I was in the room. But the smell didn't go away. So on the other day, I turned on the ventilator for some hours and it got better. It was definitely coming from the bathroom.
One more, I found sample sized shampoos in the bathroom. I don't know if she left them for me to use, anyway I noticed that they were not really clean and new. The rest of the room was quite clean but I was very uncomfortable with the smell and used shampoos.
