Hello Victoria,
We were concerned too regards to transfer times,although I do love the coach transfers personally,I didnt relish 3 hours stuck on a coach.
we went at peak time and our transfer was 1 and half hours could been a little less but I was too busy trying to look at everything as we
drove through different areas to take no notice of the time,return was around an hour having said that to me it seemed much quicker I had
got quite comfy on the coach and was enjoying the scenery so was strangely put out when we arrived at our accomodation,weird person
that I am as my other half called me when I said with a pout! ohh we here are we...........As I could have sat a little longer taking in the views.
Sorry ,I dont have any info on the nafsica apartments.
As smiffy has replied to supermarket enquiry that is spot on. you can get all you need and more.
Have a great Holiday.
