I am only rating this with 4 stars and not 5 because the enemy of the "very good" is the "best". Quite satisfied overall!

Dimitris was a great host. He was pretty flexible regarding the time we would me for me to pick up the keys for the studio, he was always available for anything that I might need and also resolved the only minor problem that occurred while I stayed at his place, which wasn't even his fault (the internet went off for a couple of minutes and he immediately called the internet provider).
