There are plenty of nice areas in Penasquitos. I’d say the percentage of older homes is similar to Poway. They have their share of new construction as well. Poway is nice, but I’d say it has higher highs and lower lows. PQ also feeds what I believe is the newest high school in Poway Unified as well.
So I’d say the answer is yes, there are definitely parts of Penasquitos that are nicer than what you saw. Good of you to rip on an area that somebody just said they liked a lot.
