We had a nice stay in Heraklion. The location of the apartment was great! By foot it is about 10 minutes to the center. The apartment itself is very cozy. The kitchen is well equipped and from the balcony you have a nice view and can even see the sea.
However, the rooms are unequally divided, the mattress in one of the rooms was very uncomfortable. Since most of the cupboards are already full of private things, it was difficult to store own things.
