Roy, I know someone who has bought one of these apartments and is very pleased with the purchase. I've been in them several times and the spec is extremely high. All fixtures and fittings are included, and these are very high-quality (double shower in the en-suite, italian marble, underfloor heating etc.) Literally all you will need to buy is beds, table & chairs and a sofa...
As regards the future potential, it is likely that this whole area will be a prime residential area in a few years time - with the entire redevelopment of the shopping centre just behind it, there's oodles of potential. There's a handy back exit for residents only which brings you straight to the shopping centre. From the front exit it's 10 mins walk into town, or a 2 min drive to the Tuam road if you work around that area.
Also, the gym/leisure facilities etc are a fantastic bonus for residents.. All in all a more worthwhile investment than some of the more "cardboard" developments that have gone up in Galway recently....
