Yes, there are local Car Hire firms down in the town (10 min walk) and there is parking at the hotel. I’d make a plan of where to go then you’ll see if it’s worth it or not. Local buses to Heraklion are good and there are plenty of shops in the town offering tours of the Island’s sites so you should be able to plan quite easily 👍

There is a short cut down to the beach that took 10 mins. Literally across from hotel there is a road and it takes you Dow to the main road. Further up the hill is a lot of bars and restaurants not as hectic as down the front and some lovely food

Stayed in the mainsonette , it had a small kitchen area , with fridge and a camping like stove on the top , bedroom is a mezanne, large bathroom with walk in shower , if your self catering the apt just down the hill on same side offers a restruant which you can use or a 30min walk down the hill, when you get to the end of the road turn right until you come to the main road and crossover, into hersonissos where there's loads to chose from on the water front . If your eating at the apts it's buffet style breakfast and main dinner which is also buffet style. There's taxis at the bottom if you chose to taxi back to the apts and there's a big supermarket there to . The pirate boat trips a must , I booked it through trip advisor while at home cost £70 but we'll worth the money , you can just go down to the front and pay there and then but don't know how much . Spinalonga trip is brilliant to and knossos. If you get the bus into heraklion and get your ticket there on the open bus it takes you to knossos then pay there to get in . The open bus ticket is valid for two days nd you can get on and off as many times as you like at differant places along the way
