The location isn't too far away from Roma Termini about 3 stops away. The flats are close to San Giovanni station. The place is in a very nice apartment block and I was greeted by Laura's father. He doesn't speak much English and I don't speak much Italian but we managed to communicate just fine and got some good tips from him. The room is small and has a single bed which I fine. The room is clean as is the bedroom. WiFi I found worked best with the Ext one. Breakfast is at a nearby café. The food was OK, not amazing but the place looked very hip and the staff were friendly. They even looked after my luggage as check our was at 10am and my flight was at 7pm.
All in all, I have no complaints and it was a pleasant stay. No noise from other guests and even nice to bump into a couple staying there. So I hope you have a pleasant stay as well.
