We own a ground-floor apartment at Sunset Beach. We had some issues after taking possession and had to chase Hanel to put them right but in the end they largely did so. The one we haven't resolved is of an annual recurrence of (rising?) damp, though to be fair Hanel have never been able to see it because our rental company persistently made good in readiness for the season before we could get out there to show Hanel the problem (against our wishes). We intend to pursue it with them next year.
You should be aware that we (all owners) are presently in dispute with the former site maintenance company about an alleged debt. They "resigned" late last year and Hanel have stepped in with a manager and are reported (by others as we haven't been there) to be doing a good job and have got the finances under control. They are our allies at the moment and relations with the site manager are good.
We really like our apartment and SBC is a lovely place to stay.
If you do decide to buy on a complex, make sure you understand how much the site maintenance, council tax, electricity and water are going to cost and who controls the site maintenance purse strings. Ideally it will be the owners, who will have elected a committee to oversee the maintenance company. We are working towards that at SBC.
Finally, we have switched to Joy Lettings for rentals this season and they seem to be doing a good job. We have just received our first payment.
