We had a really great stay in Argyro's apartment! It was really easy to get to via the metro from the airport. We were greeted by Mimi's who checked us in and showed us around the apartment, he was very kind and helpful. We didn't have to use public transport at all as the apartment is in easy walking distance of all the main attractions. Some of the reviews made us weary of the area however it really wasn't that bad and I can't say we ever felt unsafe! My advice would be to always go left out of the apartment and return the same way and you'll be fine. Definitely recommend!
