Hi, firstly I am very envious that you are staying at Nikos, you will want for nothing especially bath towels. We stayed for 3 weeks last summer and my boys 6 & 8 had the most fantastic time.
The towles are changes on average every 3 days, there is air con available. Its a fair walk to the beach for a little one, but worth it. I would recommend a torch for the buggy if you come home in the dark.
I could go on for ever raving about Nikos Apartments and Vasilis the owner, the only downside was I put on a stone!
