Konstantina's appartment is perfect if you look to stay downtown, really easy to find from the airport (we came with the city bus). Konstantina made us an easy-living with some sweets and a bottle of white wine at our arrival, very pleasant, and all you need to see (museum, sea, etc) is about 10/15mn by walk. Everything was clean, useful, etc. We (2 adults and two childs #4 #7) do recommend the location if you'd like to visit Iraklio for some days.
