Staying with Stefano was good. He is a very nice man. He provided us with cake, bananas and a map. The check-in was easy even though our train was delayed and we arrived late in the night. Thank you for waiting for us.
It's a 15 minute walk to the metro B which is the same line to Tiburtina and Termini.
Make sure you know that you can not use the kitchen. I misunderstood that because it was possible before for other guests. My mistake. It would have been nice to have a water boiler in the room, though. The bed was comfortable. We had some troubles with the shower, because it takes a few minutes to get hot water and then it only stays warm for a few minutes. Unforunately, the bathroom and the toilet were not always clean.
