I live in compass court south - its way better than Waterville. I work just up in ballycoolin so waterville would have been handier for me as its 2 minutes down the snugborugh road, however Compass court south is only 10 minutes if you come up by Cappagh Hospital anyway.
Royal canal park is a great area, we get a free gym membership, great bus service, loads of parking, near train station, cant hear neighbours in their apartments, good security.. blanch is too far from town and the traffic is a nightmare, plus i highly doubt waterville offer the same perks as royal canal park.
