This is the most negative review I have written on AirBnB but I will try to be as fair as possible.
The apartment is small but just as shown in pictures, very cute, charming. Two full bathrooms, which is an unexpected luxury in a one bedroom apartment.
Location is unbeatable, just a few steps from Istiklal Caddesi and Galata tower. If you like to walk, you can walk to Sultanahmet; if not you can walk to the river and take the tram.
There is a little noise from the street.
Somebody practices drums downstairs, although not later than the evening. It wasn't a problem for me, but you may feel differently.
There was a minor water leak in the bathroom. Not a huge problem. I informed Nevzat and he said he would have someone come look at it, but nothing was ever done about it.
Halfway through our stay the heater/air conditioner unit in the bedroom started to malfunction. It would turn on and off every few seconds, making beeping noises every time. I informed Nevzat. He didn't do anything, but it stopped for a while, so I told him it was OK. Unfortunately it started again at night, and the only way to get it to stop was to cut off the electricity to the whole apartment, meaning there was no heat and it was impossible to charge phones, turn a light on, etc. I informed Nevzat the next morning, and he said he would get it fixed after we left. I told him I wanted it addressed sooner, so that I could sleep that night without cutting off the power, and he said he would come take care of it that day. He never did, so we had to cut off the power again that night.
I was not at all happy with the lack of resolution of problems while we were staying there.
My girlfriend says that in spite of everything, she would still recommend the place to her daughter, because the apartment is so nice, and the location so good.
