Since spoken English is not very common in Turkey generally, you can easily communicate with Nicola and get what you want. The apartment is exactly as described as cozy, and he used a clever setup in such a small space. In any case, it was a pleasant place to spend our vacation. The location is excellent because it's close to Istiklal Street but quieter, which is what I prefer.
In short, this is your best choice if you're seeking for a compromise between price and quality.
Thanks Nicola
