My partner and I stayed at the Letsos apartments this year, 02/05/04-09/05/04, are had been a bit concerned after reading the previous comments. I am glad to say we were both delighted with our accommodation. The rooms were cleaned every second day (perhaps because it was the beginning of the season). The owners are extremely friendly and couldn't be more helpful. Nice quiet location. The only drawback was that some activities did not start on the island until the 2nd week of May, including scuba diving at St Nicholas.
Car hire - do not go through your rep - we were ripped off for approx £60. Pepppas car hire is highly recommended-good rates and full insurance cover. Very friendly people to deal with
We will definately be returning to Zakynthos - probably in September this year.

Just returned from a week staying at the Letsos Hotel. This is the second time myself and my partner have stayed here - we were there two years ago (and Eleni and Yanis remembered us - for all the right reasons, of course  ).Once again, excellent accommodation. Can't fault the cleanliness at all. Sheets changed regularly and change of towels half way through the week. Again, the towels aren't great, but take your own! Great location if you don't want the hectic lifestyle offered at Laganas in the south of the island. Beach is a short walk away, with plenty of watersports to choose from - recommend hiring a motor boat from Hotel Valais (blue hut on the beach), 70 Euros for 5 hours, great value and you can do your own tour of the Blue Caves. Makris Gialos halfway up the coast is excellent for snorkelling - lots of fish in clear blue water.

I know there are negative reviews for the Letsos, but remember folks it is Greece, it is Kosmar, it's low cost and it is self catering - so don't expect 5 * . Eleni and Yanis are happy to recommend trips if you hire a car, and will help you brush up on your basic greek if you ask
