Very good hotel, which I definitely recommend. Excellent location, spotlessly clean, and the staff -- everyone -- were lovely and efficient.
Even the cheerful housekeeper spoke English, and left animal sculptures made from our towels, on our bed! Generous breakfast buffet, including make-your-own authentic Greek coffee. I was impressed that the hotel participates in a plastics recycling effort; one leaves all the little shampoo tubes, etc. aside and the housekeeper disposes of them properly. Bike rental was a breeze: the front desk phoned for us to be picked up and taken to the bike shop, and at the end of our stay we simply parked the bikes at the hotel and left the keys at the desk. Absolutely nothing was difficult -- Kos proved to be a wonderful place for a holiday!
