We enjoyed our stay at Stephen's place. The private rooftop terrace is a real gem and we spent many hours up there watching the ferry traffic and the sun set on the hilltop churches. The apartment is large and spacious. Off-season, it was quiet.
We used the downstairs bed and found it to be comfortable, but found that it makes a lot of creaking noises when you move even slightly. We used the clothes washer a couple times but found it didn't wash well and left the towels smelling musty. The kitchen was not very well equipped with just the absolute basics. The non-stick pans are so heavily used and scratched that we didn't feel comfortable using them because black Teflon is flaking off.
That all said, overall the package is very good. Views are nice, parking easy, wifi great, easy driving in and out of the fort, and pretty much as-described. I'm giving it 4/5 stars. If Stephen would provide better kitchen equipment, that would probably be enough to bump it to 5 stars. I'd stay again.
