First, I'll say all the positive things about my stay. I was able to check in around noon, which was very convenient and unexpected. Usually, you can check in only after 2 or 3 pm. It's a 2-story apartment with enough space for 3 people. So plenty of space for me being a single traveler. The location is just 5 minutes by foot from the Isticlal pedestrian street.
I'll also mention some downsides to prevent guest disappointment. On the first floor, the window was broken\malfunctioning and couldn't be fully shut. Thus, it was cold in the room. i could only sleep downstairs. However, on the basement, there were no curtains anywhere. So, I had to avoid switching the light on in the dark not to be seen by the people outside. Hopefully, these 2 things will be taken care of.
