We booked a room for two persons (me and my friend). The quality of the staying place is as good as any hotel. The room was quite close to Roma Tiburtina station from where we have to catch our train to Florence. Hence, the location was perfect for us.
One minor thing was that as hardcore football fans we missed the champions league final as there were no TV channel which was broadcasting the game (may be only premium channels do).
However, we have nothing against the room. It certainly deserves 5 star rating.
