Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.

No fare history for this route yet, so this ranking is climate and crowds only — the price column will fill in as the scanner collects.

Rain days are the days with at least 1 mm of rain, as a weather station counts them.
Weather read at Kos Town, 21 km from the airport (KGS): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

Your embassy — : how to reach your embassy or consulate abroad. A guess from your city, : a city is not a passport.
