We have just had a pleasant 4 day stay in Heraklion. The apartment was as described only it was on the 4th floor which I do not remember being mentioned. Christos and his son were there to meet us and the apartment was well cleaned and spacious for 2.
We only saw Christos and his son briefly for the handover of the keys so there was no interaction with them which was perhaps a little disappointing. The apartment was obviously occupied when not being used by guests and had all the kitchen and other items associated wth day to day living. It was not explained to us what consumable items were available to be used so a trp to the near by supermarket was quickly required. (not a hassle)
The apartment has a pleasant balcony wth veiw of the distant mountains and is conveniently located just outside the city walls.
As with most of Crete signage/information is minimal at best so a good map of the city is essential.
