The parking can accommodate large vans (6m length, Hymer Free 600 Ducato Maxi) but it depends on day/season. We parked there in June on a Tuesday evening. It was 2/3 full. Price is now 200 Turkish Lira (like most central /port side parking places around tourist towns. It has 24h surveillance and a polite attendant. Didn't ask about electricity but we have solar.
