Hi Jessie,
The main limitations here are a curfew (11 PM to 6 AM) and the Provincia Border Restrictions (Comunidad Valenciana). I hope your flight will not leave you to travel during these hours. You can have more info here : https://www.bayradio.fm/2020/10/29/puig-announces-the-closure-of-valencian-community-borders/ - At the Alicante Airport, you will have to show the Spanish Form for COVID (https://spth.gob.es/) and they will check your temperature (therm cam, very quick).
I recommend you to travel with a copy of your rental contract (and possibly your NIE with you if you already got one) because you must be in position to prove a justified cause for travelling.
At the airport, you can go to Altea by taking the Alsa Bus to Benidorm (about 10 €, 1 every 2 hours), and then take the Tram heading to Denia at the Benidorm Intermodal (1,35 € - 2 mn walk from the Bus Stop / Station) with 4 stops in Altea that shouldn't be more than 5 mn away from your place.
Here is the link for Alsa : https://www.alsa.com/fr/
I wish you a safe travel !
