I had a great time in Alev - Istanbul was my favorite part of my journey! The upstairs room gives all the privacy you need, but I also had a great time chilling with Alev in the living room downstairs :) Just be aware that the ceiling upstairs is very low as it's a converted attic.. I'm 5'7" and definitely hit my head on occasion, though there were parts where I could stand fully!

Alev invited me to the Yoga studio she manages, and I ended up going every day and getting a massage there - it was lovely! Cihangir is a great neighborhood! Close to Taksim and Istiklal street, but away from their touristy craziness, and an easy walk / tram ride (if you like hills!) to Sultanahmet. I had a lovely time. I'll definitely be returning to Istanbul, and when I do, I hope to stay with Alev again!
