Car rental in Istanbul — compare partners

Two continents in one city — Sultanahmet for sightseeing density (Hagia Sophia, Blue Mosque, Topkapi Palace all within walking distance); Beyoğlu (Galata, Karaköy, Istiklal) for restaurants, rooftops, and nightlife. Hotel pricing swings hard with the lira — booking in GBP via UK merchants gives a fixed rate and avoids checkout surprises. Spring (April–May) and autumn (September–October) are the best weather windows; Ramadan and Bayram holidays can affect restaurant hours and pricing. Istanbul Airport (IST) is 45 minutes from Sultanahmet by Havaist bus or Metro + Marmaray connection; the old Atatürk airport is closed — ignore outdated guides. Avoid unofficial airport taxi touts; use the official taxi rank or pre-booked transfer.
