I was on Normando's house with my boyfriend during few days. Normando is a great host, very nice and friendly, he gave us all the informations we needed. I keep a very good memorie of Roma thanks to him. Go in the center in Roma is very simple with the train and the bus, and it's not very far from his house (around 20minutes). The room was clean, and comfortable. I recommand his house if you want a calm space not very far from the center !
