The town of Protaras itself is very quiet, there are few people on the streets, of course there are many on the beach, most with children. In shops, cafes, they don’t speak Russian at all, if you know at least a little English, it will save you, or always have a phrase book with you.
In general, people in Cyprus are very kind and hospitable. Go, you won't regret it.
I wish you all a pleasant holiday.
