May be a long shot Harry but the Romanza have well appointed sea view villas near the harbour end of the bay. From memory I think they cater for about 6 or so. They do however have 2 side by side - could be an option ? finished to a high standard I recall. Hope you get fixed up Ok.
Sellsy, have stayed at The Romanza Villas, fantastic, private pool, state of the art kitchen, TV/games room, sauna, bathrooms and showers galore, superb sea views across the bay, close to town, but only three double bedrooms.
Yes, you could book both of the two villas but that could prove to be a bit expensive.
