I have really mixed feelings about this place. For a short weekend stay, it has everything you need and is very central to the main old town attractions. The room was clean, the staff were amazing.
I stayed for a month while working remotely, and it wasn't exactly setup for this purpose.
Unfortunately many things aren't as described. This ensuite room is not directly connected to the terrace, it's on the floor below. And the terrace is actually a public restaurant on top of the building. So if you would like to sit upstairs and take in the views 'over the Blue Mosque and Marmara Sea', you'll be doing it with a restaurant full of people, sometimes it's fully booked for 'set menu dinners', where you actually have to leave.
The room itself was clean and they regularly cleaned it during my stay, but the stairwell smells really bad.
The entry to the apartment is through a crypto/bitcoin exchange office? Which is ok, actually helps you find the place easier, but is not on their directions to you.
The 'workspace' in the room has a stool, not a proper chair, so not ideal for working.
