Greg is a great host, he is very professional and very helpful. He gave us nice recommendations (eg. a traditional fest in a village close to city of Rodos), he provided us a voucher for the trip to Symi island, he is very very flexible with the check in and check out hours when it is possible. He tries to make your life easier when you're there!
The appartment is practical, it is not in the city center but you can reach both to old city center and new city center in 20-25 minutes by foot, we like walking therefore it was not a problem at all. If you rent a car to go visit different beaches and villages, it is easy to find a parking place on the road.
Highly recommended.
