Alessandro flat got everything a traveler need and can comfortably host up to 4 people. Apartment was clean, cosy and warm (we were staying at the end of february), it's decently equipped with all needed household appliances. It's situated near the train station. Trip to Rome center by public transport was a little bit more than an hour and cost less then 2 euro.
So if you want to travel to Rome on the budget and don't mind couple of hours commute - I'll recommend Alessandro place, it got good value for the price!
