I live quite nearby. Park Crescent overlooks the GAA pitch, so you will get woken up on Sunday mornings - you might also have some congregating in the evenings. Knowing how much the house is on the market for, I might think twice about it: while we've been happy living in the general area over the last five years, it has its rough element. (Plus we looked at one of those houses a couple of years ago and thought the bedrooms were desperately cramped! And I'm nearly sure the one you're looking at is now mid-terrace, isn't it?) Scout the area late on a Saturday evening and see what you think.
On the plus side, there is a good selection of schools in the neighbourhood - across in Terenure, and down on Clareville Road, as well as the local ones on St. Agnes' Road. You've got the Ashleaf shopping centre and the Sundrive Superquinn, plenty of public transport - various varieties of 15s and the 54A from Kimmage Road West, or the 83 from Stannaway Road, you're 15 minutes' walk from Terenure. A few decent takeaways too, though I'd go to Terenure or Rathgar for eating out.
At the budget, it's not the house I'd choose - but they're decent houses, and the neighbourhood is fairly okay. Some of the kids run wild, but there are a lot of very good kids around too.
If you've any more detailed questions, feel free to post and I'll answer if I can, or you can PM me if you prefer. Wishing you the best!
