Hi Florica! The thing about street perspective is to consider if the street is level or running up or downhill, as this can be a pitfall, literally!
Also consider if the street has a bend or curve.
There are many excellent books and tips on Perspective, and they will invariably use either one or several vanishing points depending upon the complexity of the scene.
Personally, I have always used instinctive perspective; if it looks right, then it probably is, but there is no real substitute for getting used to the basic rules of perspective, by practicing with a simple, straight and level street scene, with a single (usually eye level) vanishing point (VP).
If you can get into the habit to begin with of getting the perspective right technically (VP), eventually you will get it right instintively.
Another way, which I often use, is simply to look at the angles of the roofline / Pavement line by using the handle of your pencil or brush, to establish the angle to the horizontal (use the paper edge as a guide) and then just move you hand, holding the brush or pencil, to where you want that line (Roof / Pavement) to be on your paper.
I hope the above may help a little, but come back to me if you need anything else.
Very best wishes,
