Just returned from 2 weeks at the Planos. we sateyed with friends and had a wonderful time. I was initially disapointed as the rooms are a little basic, but after a day or so, this wasn't a problem. The apartments are well placed to provide access to the beach and local bars and restaurants. It's also well placed to ensure you get a good nights rest.
The pool area is not bad, even if the pool is on the small side. There are plenty of sunbeds available and the pool bar was adequate for our needs whilst in that area.
Both Tsilivi are well stocked with restauarants, all providing a typical Greek welcome. They all provide a mixture of local fare and more "british" fare, so you won't run out of places to eat.
