My friends and I stayed at this apartment for 4 days and everything was good. The communication before and after the arrival was great, the house was clean and had evrything we needed! The apartment is 20min walking from the city center but along the way there are shops so it's also pleasent to walk to the center.
Near the apartment there are also a supermarket and bus/taxi station.
We totally recommend this place if you need to stay in Heraklion!
