Nikos was kind and very fast to answer and to arrange the meeting time. The studio is as nice as you see it in the pictures, therefore it's a great value for the money.
We found the bed a little small to sleep in two people, but maybe we are just too tall people ;)
The apartment is in a very safe street, 15-20 min by car to Heraklion city center and 15 min to the airport.
Overall: recommended :)
