Greece- WIFI- how is it really?

We are leaving for Greece in 60 days and need good wifi for the 3 months we plan on staying there, this is a must! I’ve heard mixed reviews and the 8-10 ranking on nomadlist are not super encouraging. Has anyone recently worked from there? What should we expect? We plan on renting an apartment after staying in airbnb and would like to work from the place we are staying in. Thanks so much for helping me decide if we can continue on or change plans.
