We had a friendly welcome from the host after we parked our (larger than normal) rental car in the off-street parking. This house had a well-equipped kitchen (although we only ate breakfast at home) and aircon in the main part of the house & 2 of the 3 bedrooms. Good internet speeds too via the WiFi. There's a large flat screen tv too but we didn't use this. Good water pressure in the shower.
We found a very passable restaurant for dinner about 10 minutes walk away (Vardis) and a bakery for breakfast just around the corner. We also went to an excellent restaurant specialising in Cretan food (Erganos) and "Dish" in the center of Heraklion which was recommended by the host.
After the first night we were unable to park the rental car in the off-street parking as another car was parked legally but too close to the entrance for me to get into the space (probably would have been possible to park with a smaller rental car). We found on-street parking very easily close to the house nonetheless. I accidentally left my mobile phone in the car mounted on the air vents and easily viewable from outside one day while parked, but the car was not broken into. The gate to the house is lockable and we had no security concerns.
No other reviews mention this but while we were there, planes from the airport (second busiest in Greece apparently) were taking off to the west over the city of Heraklion. This is not an issue specific to this house as the planes could be heard over most of Heraklion during the day we spent walking around the city.
To sum up, we would definitely look to book this place again if we were to return to Heraklion.
