I cannot really add much to what has already been written about this hotel. It's clean, quiet and well managed with airy rooms with own kitchen, bathroom and balcony, a nice little pool, a bar and the beach right in front of you.
Balos is a very quiet spot on the Southern coast of Samos, so different from the more touristic places on the islands such as Pythagorion. Nevertheless, there are 4-5 restaurants in town that all seem good so in that regard you are not isolated. There is no mini-market though, but the bread man and the fruit man pass through the village in the morning (you'll hear the loudspeakers from their cars) and otherwise you can ask Tia for other items from the mini-market in nearby Koumeika (or you can walk up there yourself).
The beach is full of pretty stones but your feet tend to get a bit sore when you enter the sea. A pair of beach shoes for swimming is no bad idea.
