This was an amazing trip and I cannot recommend Marion's place enough.
The location itself is just perfect for Cretan holidays: Archanes is a beautiful village, very close to Heraklion and all the sites (Knossos is a small bus ride away); it's much nicer to stay in than Heraklion itself however. The people are lovely, the village is high up so cooler and with cleaner air than down by the cost, there are numerous amazing restaurants and cafés in the village, and lovely walks/hikes just from your doorstep.
Marion's villa is a beautiful old place that is just as gorgeous as the pictures show, but it is hard to convey in images how serene and welcoming it feels. The villa is small, but with a very high ceiling so does not feel cramped at all. Great care has been taken in renovating it and it shows in every detail; it's a really special place to stay in.
Finally, Marion is the perfect host. She is, as other reviewers have said, a lovely person with great warmth and extensive knowledge of the region and its history, and will make your stay something very special. Getting to meet people who are so welcoming and know so much about the place you visit is what makes a system like this unique, and so rewarding.
