We (2 adults and a ten year old) stayed here for two weeks and it was everything we needed. Clean, comfortable beds, bathroom with a shower, fridge, kettle, toastie maker and a couple of electric rings.
There is an outdoor communal area with tables and chairs and a kitchen area for anyone who wants to be more adventurous with their culinary skills.
The owners are very pleasant and helpful.
The location could hardly be better, a couple of minutes from the beach and restaurants and a 10 minute stroll to the nearest hotel with a pool.
If we go back to Katelios, we would stay here again without hesitation.
