We had a little difficulty in finding the room - but as soon as we found each other, Andrea, the host and us - it was very assuring experience. Andrea was very helpful, he allowed us to keep luggage, let us use all his kitchen and toilet materials, Andrea has a very pleasant and welcoming personality.
The room is ok - if you are not staying long in Rome - it is 20 minuites from Colloseum, near to metro station.
We will surely come back and ask aotyhers to come and stay with him.
