Super quick response from host which was very important. Apartment was clean and complete with heater in every corner (good for cold weather).
Location is at the center of most attractions (Blue mosque, Hagia sophia etc). There's also Arasta bazaar nearby (walking distance). Surrounded with restaurants, cafes and street shops.
Only downside was the stairs. There's no lift, so for those with huge luggages would have a lil' trouble going up and down the stairs.
Otherwise great stay overall. Samet was such a great host. He made sure that everything was alright and texted me everyday to check in if there's any help needed. Totally appreciate that. Would highly recommend others to stay.
