Language / Grammar questions... małe/mało [3]

Hello, from Newfoundland. :)

I'm working on a grammar exercise right now, and I hope someone will help me with this set:

1) Jest mało mieszkań.
2) To jest małe mieszkanie.
3) Tu są małe mieszkania.

I think 1) is in the genitive plural because of the ending, so I have "Is few flats." but then I want to think "Są" instead of "Jest" for "(there are) few flats". I can't make sense of this one.

2) It is a small flat.
3) Here are small flats.

I think 2) and 3) are okay, but I put them there for the comparison to show why I was confused.

Thanks for any help!
