We very much enjoyed our stay at Christos' apartment. We found it exactly as described. He was very flexible with out check in/out times. I had not appropriately considered the difficulty of walking up three flights of steep stairs with luggage, (I'm no spring chicken) but Christos even carried our bags up for us. He and his son explained all we needed to know about the penthouse and the neighborhood, and left their phone number with instructions to call with any questions.
The very best thing was the location, just outside the Venetian wall and within easy walking distance of all the wonderful things to see in the old City. The WiFi connection could not have been better.
The penthouse is not luxurious, but very comfortable. I'd recommend it all except those who might have a problem with the stairs. I'd give him five stars except for the stairs.
