Just had a super 2 weeks at the Ariadni Studios in Tingaki. These are just behind the Sunset Hotel at the top of the main street. They are set back from the road (200 yards) and are set in their own gardens. There are 20 studios on two levels. We had a ground floor studio and had a nice lawn outside the patio. The studios were basic but clean and only about a couple of years old. The owner was there most days and was very approachable. Facilities such as pool etc at the Sunset available for Ariadni customers. The Sunset has a luggage room for use on the day of returning. Very useful when your flight is at 3.30 in the morning.
Tingaki consists of a main street with loads of tavernas etc along with truly tacky tourist shops. Better to get stuff in Kos Town itself. Tried many of the tavernas but our favourite was the Taverna Syrtaki. Proper traditional Greek Food, no pizzas or chips. It is run by Lakis and his wife Adreana. Lakis is completely mental and often starts singing and dancing at the drop of a hat. Syrtakias actually means "Dancing Man". He is also a great practical joker. When busy, as it often is, service can be a bit slow. Who cares as the food is superb and worth waiting for, besides who wants to rush when on holiday. The Grand Salle is also worth a visit.
Went on a couple of trips booked through Theokritos Travel on the main street opposite the Meni Hotel. All the tours are guided by themselves and they have there on air conditioned bus driven by the owner Nikos. Went on the island hop to Kalymnos, Plati and Pserimos. A busy but thoroughly enjoyable day. Rik, a young chap from Lancashire, was our guide and had lots of information about the islands. Also went on the touristy Greek night with them. Well worth the 25 euros. Food was out of this world, more winr than you could drink and non stop cabaret of greek singing and dancing. I can recommend using the Theokritos gang (Nikos, Louise, Sharon and Rik) for any trips or anything you want to know.
Would I go back. The answer would have to be a big fat YES.

JONATHON STUDIOS - fairly new property situated on the coast road about 3 to 400 yards from Tingaki Square. Passed them most days on my way to our favourite spot on the beach. The beach is opposite them and they look OK.
