This apartment is perfect : Clean, comfortable (especially the huge bed).
it also has great central location, close of shops, restaurants, bars, supermarket and at 10mn walk from Central bus station, which makes very easy to leave the city for excursion when you do not have a car.
Stelios was super reactive, flexible and informing of special events taking place in the city.
if I return to Heraklion, I would definitely pick up his apartment.
