What can I say. The apartment was in an incredible location (near the Blue Mosque, Hagia Sophia etc). The room was insanely cosy, great jacuzzi, but by far the best part of the apartments were the reception staff. They were so, so helpful with recommendations, helping us book a taxi (at a lower rate than Uber on a Saturday to the airport, madness), free tea, coffee and biscuits every time we came in or out, and finally they were great fun. I can't quite remember his name (sorry if you're seeing this, I have bad hearing), but one gentleman with glasses and a sore tooth was great fun.
Highly recommend, will 100% use again.
