We were 6 adults staying at Villa Aspes for 5 days in May. Korina was a five stars host and we had a great time staying in her villa. She proved to be more than helpful in finding us a private speedboat to Serifos (seamen were on strike when we arrived in Greece). We wouldn't have made it to Serifos otherwise. She also proved to be highly reactive to our other questions/demands (eg extra chairs & blankets). We were also very happy with the villa and had much pleasure enjoying the view from the terrace. In addition, at this time of the year, we were delighted to feel like being the only visitors on the island...
The only thing to keep in mind when booking the house for 6 adult people, is that there are "only" two rooms (with very confortable beds I must say). The two additional persons therefore get to sleep on the sofa or a camp bed, not as comfy as proper bed.
But this didn't shade our overall experience and without any hesitation, I definitely recommend this place !
