The location was perfect! Right next to the Sultanahmet area which hosts some of the major attractions of Istanbul like the Hagia Sophia, Topkapi Palace, the Blue Mosque and the Basilica Cistern. It's just a 5 minute walk away from the guesthouse. They are open 24 hours making it very easy to come back whenever and get your keys. They were super accommodating and even allowed me to keep my luggage during my last day after checkout. All in all, highly recommend!
