Hi JHC and welcome to CBF.
I haven't personally had dealings with Manzara but they have been very prolific with their house building programme in recent years, and it would seem that their properties are generally snapped up off-plan. There are 2 developments with villas in Calis (one very close to the beach - one for sale there and the other is closer to the upside bridge/BM Blvd, again, one property for sale).
As far as I'm aware they are a good reputable company. Good luck with your purchase!
