We didn't meet Jul, but he was responsive to texts and emails and returned inquiries promptly.
The apartment is adorable and just like the pictures. As others have said, it has a great view, and you can see the acropolis from the sleeping loft. It is generally quite comfortable with an air conditioner, good shower, good location, washing machine, and a well stocked kitchen.
The place is fine for two, but with three people the benches are not well padded for comfortable sleeping; better pads could help. In general, more attention to bedding and mattress care such as better fitted sheets, (the sheet kept coming off the mattress,) and bug proof mattress covers are highly recommended. Other nice-to-haves would include some extra chairs to make more flexible seating; a few hooks in the bathroom to hang towels and some space to hang clothes and unpack, as most of the closets/shelves were filled with personal items.
