They were extremely nice and helpful, I just cannot express it any better. I definitely suggest you to give Hotel Catherine a try once you visit Kos.
The location of the hotel is perfect, you can reach sea cost within seconds, you can walk to old city town within minutes and to use station its very easy as well.
I went for beaches in the day at different bays by bus and then came back for dinner at the centre. It had been very easy for me to walk anywhere from the hotel.
Lastly, I knew Greeks are very welcoming and warmhearted. But at Hotel Catherine, I realized that they are much more than that. Thank you very much for being nice to me.
