Hi Hal,
Just come back from holiday and seen your post. NO, there is nothing seriously wrong with Balcones at all!! We've lived here permanently since August 2008 and can honestly say that we love it!! Like any other new development it's had one or two teething problems - but not many - and Rudina, the developers, have helped as much as they could to solve any problems quickly.
Our electricity works fine - and , although it seems we've had to pay excessive amounts to Sevillana for connection, and upgrade to more Kw, it won't mean we USE more electricity over a month, but it will mean we don't get the fuses tripping all the time - especially in winter!!
All we can tell you is that there are some very friendly people who have completed here, and the views are spectacular - winter or summer - it's a lovely place to live - or holiday.
If there's anything else you'd like to know just send us a Private Message and we'll do our best to help.
Phil and Cath
