Overall, we had a nice stay and enjoyed our time at this place. This is a beautiful and historic building right next to Galata tower. You will enjoy all the great things this neighborhood has to offer (restaurants, bars, music, etc) and you are within walking distance to metro stations which makes it very easy to visit different locations without dealing with the heavy traffic. The property managers were also very responsive and helpful. Overall, I would recommend this place, but I think there are some minor things that the property managers could improve.
It is worthy to note, the rooftop offers a beautiful view of the river and Galata tower. But you have to climb 4+ floors to get there and there are no lifts available in the building.
There are two main bedrooms in the apartment. A master bedroom, with a bathroom inside the room, and a guest bedroom, with a detached bathroom. The bedroom that is listed a 3rd bedroom, is a very small room inside the master bedroom, which is really the size of a "small walking closet" with a tiny bed (smaller than a twin bed) in it. So keep that in mind, if you are renting this place as a 3 bedroom.
There are a few things that need improvement:
1- The bed frame in the guest bedroom (the room with detached bathroom) is old and not in a good shape. The frame itself (not the mattress) is very noisy and not flat, and has a large bulge in the middle and when you lay on it, you feel like you are on a slopped surface which makes it very difficult to sleep comfortably.
2- The windows in the apartment (particularly the guest bedroom which is overlooking a busy street) are old single pane windows with zero soundproofing capability. This apartment is located right next to Galata tower, and you will hear loud music, people laughing and talking every night until 2-3 am. You can get a few hours of sleep, before nearby mosques wake you up around 5 am with their loud calls for prayers. And then around 6 am, trucks come to deliver supplies and food to restaurants, shops which are located right next to this apartment, and you can hear them unloading boxes, gas tanks, etc, so you can barely enjoy more than 2-3 hours of sleep given the windows do not provide any sound proofing.
3- The faucet in the detached shower is very difficult to use. The water is either very hot or very cold. It takes about a minute to two to figure out a sweet spot where the water coming out of the shower is comfortable to use, but a few minutes later suddenly the water becomes too cold, or too hot, and you have to close the faucet and redo the process. I think investing in a new shower faucet will fix this problem.
4- There are no toilet paper holders in any of the bathrooms. So you either need to place the toilet papers on the floor or hold it in your hands, which is not comfortable/clean.
