Sorry Merlot - major computer failure at work on Friday so couldn't reply. Glad Stoupa looks like it might be what you are looking for. There are two supermarkets along the main street on the Stoupa harbour, and a very good bakery just off the main road. So plenty of stuff if you want to self cater. There are a few day trips can be done from Stoupa, depending on your dedication and inclination. Archaeology doesn't tend to figure very highly on our DDs list of things to do and see, so we stayed in the area. There are some great caves a bit further down the coast that make a good day out. There is a Stoupa discussion forum here: http://www.zorbas.de/webcam/camboard/ if you want to ask the experts.
I have been in one of the two beds - and it was only newly built at the time so didn't have any garden around it. I have a feeling the two beds are closer to the pool than the one bed we were in, which I think would be nice. They are all high quality units with really very well equipped kitchens, and George (who runs the place) is very fastidious, so I am sure the 2 bed will be lovely. You will have a wonderful relaxing time. The restaurant on site is more pricey than the tavernas in town, but it is fab food so its worth eating there at least once. And the beach just over the headland from the main Stoupa town is actually nicer than the town one, so don't forget to try it. And report back!!
