I stayed in hotel Koala on July 2011 and my experience was definitely good. Location is good (10 minutes walk to the central area), rooms are equipped with air conditioned (for free) and mini fridge. There is free wifi although the coverage area is quite small. The swimming pool is quite small but actually I didn't go to Kos for the swimming pool so it was not a concern.

The owner Dimitri and his mother are extremely gentle and they will explain you everything you need, from place to visit to buses... It's rare to find so nice owners !

The only thing that should be improved is that t they don't usually change the towels, but some friends of mine asked to do so and they did, so just ask, they will satisfy all your needs.

i spent here the first 2 weeks alone, but never felt alone. This nice family who owns and works here took me in there arms. it was more" friend-friend" than "customer-employee".
Everybody is asking how i feel and if i need something starting from the "Mama" who works on the afternoons, Dimitris (son and manager) at the front disk on the mornings and evenings, Angelo in the bar for the night shifts, Sister.. and they know everything about this island and they always have the right information.
the room was clean, quiet, has all basic things (TV, extra blanket, air condition, fridge..). the swimming pool is clean, the temperature of the water is good. the bar has everything you need to start a successful evening with Angelo behind the bar you never feel bored with his sense of humor, they even have a happy hour from 19:30 to 20:30.
There is a shop on the other side of the street, the beach is a five minute walk away, many good restaurants near by.
i think I've spent an excellent stay here, I'm sure it could be less interesting if i stayed at some other hotel. four of my friends joined me here for my last week, and it was nothing else but fun.. :)

Location of the hotel is ideal. We stayed 10 days, rented bikes and (for 1 day) a car. Have explored the whole island. Very friendly family hotel, always helpful, simple but good breakfast with bread, cheese, ham, marmelade, Greek yoghurt with honey, large bedroom with good matresses, excellent hot shower in a small bathroom, pity that the shower curtain was too small. Radio did not work.Room was very quiet during the night, except for some fighting cats. We had the swimmingpool all by ourselves the times we were there and that was like paradise. Room was cleaned every day. There was free wifi, but most of the time no good connection possible. Regarding the price it was above expectation!

This hotel is very basic, but worth it if you get a good rate. Not completely in the center, so a bit quieter if you want some peace. Hotel staff very friendly and helpful. Basic breakfast. Don't try to take a nap in the afternoon though, housekeeping gets a bit loud.. I think I would go back.
