Bring your own WiFi
I’m currently with my family on vacations and we have rented a holiday flat. The description of the flat includes “Free WiFi”, so I would assume there is a functioning WiFi. It may not be fast, but it should be working. But my experience with WiFis in hotels and holiday apartments (at least here in Germany) told me, to better take some precautions and bring my own WiFi repeater with me, which I could also use as an access point when there is access to LAN.
