I haven't personally met Dimitri but Danai (hope the spelling is right) was super helpful. The check-in was extremely quick and she gave us useful tips on what to do around the area. The flat is huge with loads of natural light and with a very young atmosphere. Close to the historical area (20 minutes walking). The bathroom was a bit rusty and we found some dust here and there but for that price is more than acceptable! Overall a great experience!!!!
