We really enjoyed our stay, Susan's house was as described directly opposite the beach with a fine seabreeze cooling the house on most days.
If the seabreeze was not in action it tended to get a bit hot but there were no crazy hot days during our 6 day stay.
The beach is divine but a bit rough for swimming, local knowledge led us to other swimming friendly beaches close by so no problem there.
We ate out every day so didn't use anything more than the kettle and fridge but I'm sure barbeque people would enjoy the back deck barbeque provided.
The only thing I can think to suggest would be perhaps provide more than only 2 tea towels and get an ironing board. No ironing board was a bit weird, we were there for a wedding and needed to spruce up.
All things considered, the house was exactly as described and we enjoyed our stay.
