Lots of hills. Kos is like every island, tourists area is clean, outside that is not so clean.
Lots of shops, the haven, places to drink and eten are plenty of course ??.
You can go to different beach. We went in October which was cold in the water.
Over Aegean View Aqua Resort:
Hotel is good. Rooms are good, they just needed to check things a bit more and pillow cases have holes and stains on them. Had to ask to change it. Every day the change of towels and the pillow cases, which still have stains on them????. Sink is not been clean. Under the bed is full of stuff.
No hot water, had to asked then we got hot water.
But even with all this, it's a very nice place. They are so friendly people. In the restaurant the food is very nice, always something for everyone ,different choices every day They made gluten free pasta, spaghetti and bread for my husband. All in all we would go back there, but not in the summer, apparently its too busy!
Make sure you take an coat, cardigan, it was very cold and windy in the evening.
