We had the most fantastic honeymoon at Locanda Degli Agrumi, with owners/hosts Salvatore & Rita offering friendly service and happy to help with anything we needed - including a personal lift from Salvatore to meet our shuttle bus for a daytrip to Capri.
If you are looking for a lively resort then this is not the place for you, but if you want a quiet, relaxed stay somewhere with a lovely (cheap!) restaurant (La Polisportiva) with incredible views and tasty food within stumbling distance then I would highly recommend it.
The only minor downside is that the buffet breakfast can get a bit samey with just a variety of fruit, yogurts and pastries on offer, but is still very tasty all the same. And the freshly squeezed orange juice and lovely coffees go a long way to making up for this.
Also, whilst this is not necessarily a bad thing, it's worth noting that Conca Dei Marini itself is quite quiet and a little out of the way - and only one (decent) restaurant is really in comfortable walking distance from Locanda, so I would say a hire car is a necessity, not a luxury. This means that (in August at least) you will end up paying a fair bit on parking as it gets very busy...
