We really enjoyed our stay at Kings Blue Luxury Residence. The house was really cozy and modern and it was just like the pictures. It was really close to the city center of Heraklio (a couple of minutes walk) and you could find everything at the neighborhood. The host was friendly and always available when we needed him.
The only con at the house was that according to the light sometimes the shower and toilet door (which was made of glass) was a little transparent (you could see the figure of the one who was inside), but it was not a con that cause us any dissatisfaction.
My friends and I highly recommend Kings Blue Luxury Residence for your stay at Heraklio.
