We only stayed in Kos one night as a stop over on our way from Santorini to Bodrum - catching the ferry. The room was okay, clean but a very small bathroom. It is located very central, so walking distance to the Main Street of Kos, but the walls in the room were very thin so it was very noisy. The room was fine for what we needed it for - just a place to sleep for the night, close to the port - but we probably wouldn't recommend staying for a longer period of time. Our host was lovely though, very nice, friendly, hospitable and helpful.
