About 45 euros, 1.5km about 20 minutes walk. As for best beach, not the nearest as we thought is was dirty and full of hawkers. Not a patch on Malaga or Alicante.

I think the taxi from the airport was around 40 euro, don’t remember exactly. We didn’t go to any beach but there’s a few to choose from. I think the closest is about 12 minutes by taxi, or 30 minutes to walk and another one is a 45 minute walk . Buses reach both destinations from the hotel and take 17 minutes for the closer one and 30 minutes for the other.
