I stayed at Valentina's place in the early days of May. I stayed 4 nights on my own and first trip to Rome. I stayed in the small room that has an en suite bathroom. The room is in a charming apartment-building, in a nice area just beside (pretty much across the road from) the Vatican City and St Peters Church. I didn't meet Valentina, but met her co-host, who was nice. The room was very clean and everything felt fresh and new. The bed was comfortable, the pillows were great. The bathroom is completely new, with an amazing shower. The towels included were on the small side but as it was just me I used both of them which worked fine. There is a kitchen available, and it was also very clean and fresh. Wi-fi was fast and stable all throughout my stay.
The breakfast included is tokens you can use for a cafe 30 seconds away from the apartment, and it tasted very good. The street is super-quiet in the evenings but in the mornings you can hear cars drive by if you have an open window. There are three locked doors you go through to get to your room. The apartment-building, the apartment and your room. Even though I was staying on my own I felt very safe because of this. It also made me feel a bit like I lived in Rome, which was a cool feeling!
I walked into central town every day, I am a fast walker and it took me maybe 20 minutes. It is a great walk, walking past St Peters Church and across the river. There is also a bus-stop 1 minute away from the apartment, where the bus takes you into town in 10 minutes. But I would recommend walking, as there is something to see round every corner!
All in all it was a perfect room for me, and I think it fits for a one-night stay as well as a long-term stay. The location and the room gave a real Rome-feel and I will definitely stay here again when I go back. Grazie Valentina!
