Overall, this place was okay.
It's located in an older building with a steep stairwell and no elevator ( be prepared to get your luggage upstairs somehow). As the building is not new, some things are just expected - awful soundproofing, wooden frame windows. We stayed in an approx. 10 sq m room, which had a "unique feature" - bathroom wasn't actually a separate room, but rather a nook separated by a glass (yes, it's see-through even with a curtain) door. So if you are travelling with your loved one - make sure you are comfortable heading ALL kinds of sounds.
The bed was decent enough, though the management of the place forgot to give an extra blanket that we requested 2 weeks prior to the trip. We found ourselves lacking a room-sized trash can and bath mat. And oh yes, if you are a person in a larger body like myself, get ready to accidentally turn off the water in the shower all the time.
We'd like for the owners to be more diligent with cleaning - decoration on the walls and some shelves definitely needed some dusting.
Be prepared that there is a mosque right next door and it will wake you up every morning at 5 AM.
The place is located next to Galata tower, also 3-4 minutes away from the metro station, which is great.
