Hi Susan
Stayed here last August and I'd say it's a bit more than a 20 min walk to the beach, BUT the dolmus stops right outside and they're every 10 mins or so. We usually walk everywhere, but for us it was a bit too far out for that - don't let that put you off though

We got quite used to hopping on and off the buses every day and night, and they only cost peanuts haha
If you go to the Majestic restaurant, you'll have a free lift there and back too.
The apartments are cheap and cheerful, plenty of hot water and there's always something going on. The 2 pools are great. It was nice and breezy round the pool with the aparts being so far back, a def bonus for us
Hope this helps, and feel free to shout up if you've any more questions.
