Here is a little rhyme that I learned along the way......"How you feel and where you are, always use the verb ESTAR".
The verb estar has various uses including the geographical or physical location of a person or item.
El café is the coffee so if it's also cafe (as in cafeteria) context seems to be the only way to tell the difference.
Can anyone help? why the use of "del" here instead of "de". I am still trying to understand when you use, del, de, etc
Del is just the cotraction of the preposition de and the singular masculine article el. Since you're talking about the distance from a certain supermarket, you would say "el supermercado", but since you need a de in front, it becomes del.
There are only two contractions in Spanish: del, and al, which is made from the preposition a with el.
You would not say this in English. You would say something like "The cafe is quite a way from the supermarket".
