You would be welcomed at Anamnisi Coffee shop in Chania (see Google maps) where you will meet not just English people but Greeks as well, all of whom speak English. The coffee is FREE!! although you can make a donation if you want. From time to time we also get visitors from other countries. On Thursday morning from 10.00am to 2.00pm we welcome many foreigners who come to use the showers and washing machines. It's a very interesting time!
If you come to Crete permanently, you should try to learn a bit of Greek by mixing with locals - but they are keen to use their English! In September we will re-start Greek classes.
