We enjoyed our stay at Kaliannas apartment. She was really nice and welcomed us even late at night and gave us nice tips what to explore around Heraklion. The apartment was very comfortable and nicely furnished, all necessary things to cook or for the bathroom (like a hair dryer) were available. You should be aware that you are staying in a bigger city so it's perfect if you enjoy the city life (the old part of the town can be reached by foot in about 10-15 Minutes, the beach is a bit further away but easy to reach by bus) but maybe not the best if you are looking for a quiet and peaceful vacation.
