I wouldn't be to concerned about stable/fast internet. I currently work out of hostels and cafes in Medellin, Colombia. Free wlan everywhere and haven't had any more problems than back in Switzerland. And since I have a local cell phone, I can just switch to tethering if there are any. Europe has a lot of amazing cities I could imaging to stay longer, but they have very different cultures and styles of living. In my opinion it comes down to personal taste rather than any other concern (except maybe cost of living). Instead of moving all you stuff to one place it may be better to store it in your current place and just come to Europe with backpacks and travel for a bit until your family finds a place they feel like settling.
