Grigoria was an excellent host! She was very welcoming and communicative. The space was absolutely perfect for two. Definitely give yourself some time to have some wine and sunbathe on the patio-because I sure wish we could have.
The location im Heraklion is perfectly fine- highly suggest renting a car in Crete though. The drive to the city center is around 10 minutes, not really walkable though. We did wish we would have spent part of our trip staying in Chania, just because it was more central to what we were most interested in, which was beach hopping around the island.
Grigoria recommended Peskesi for dinner. You must go. Make the reservation right now. It was the best dinner we have ever had in our life and very reasonably priced with stellar service.
If you're traveling around to different beaches, just trust me and go to Seitan Limania and Kedrodasos. They were breathtaking, and much less crowded than some of the other beaches we went to. Do keep in mind the solid 15 minute hike down (bring sneakers) to each of them once you arrive.
