We have just returned from a stay at the Filoxenia Apartments. Like others we had read some mixed reviews and were slightly apprehensive. As mentioned before there is no air conditioning, which made the nights quite uncomfortable, you could hire a fan for 10 euros a week but when we asked there was none left. However we were told that they should be installing air con next year.
Rooms had everything we needed. Hot water only seemed to appear in the evening but this isn't too bad when it's really hot weather!
The walk to the beach is not too bad at all, takes about 10 minutes. It was nice to be set back from the main road, in a quiet area unlike the Mythos apartments, which are right on the road.
Angelica did have friends to visit but she was still happy to serve drinks and food and she is there so much of the time, that I can't really blame her. However she did leave the restaurant/bar unattended quite a number of times to go and pick her kids up from school.
For really good authentic food we would recommend the Garden restaurant (street behind the beach front) and Ostria Restaurant (this is one of the beach front tavernas)
If you are happy to sit by the pool and beach for your holiday you can do without a car but if you want to explore I would recommend hiring one. We booked with CBR when we arrived but having chatted to other people it's a lot cheaper to pre book with a company like HERTZ and pick your car up from the airport. If you do hire a car don't book the island delights tour because you can do it all yourselves for half the price.
Katelios is a lovely resort and we had a very relaxing time
