Perfectly located & super clean little apartment with a beautiful sunset view of the harbour directly from your bed!
As others have mentioned, there is a flight of stairs to enter the place so if you have problems walking or carry a pram or similar, this would probably not be the place for you.
If you are a light sleeper you may also want to bring your earplugs as Heraklion's airport is very close to the city centre and you can hear planes at night... That said, I slept like a stone here without any plugs :)
This little downside is completely overruled by Maria's great hospitality though, with an almost filled fridge and some fresh grapes waiting for you to refresh you from carrying heavy luggage in the cretan sun :)
