Tolga's apartment is in a grate neighborhood, with lots of cafe-cool-places & vintage shops. It's 10 min near Taxim sq. and close to public transportation .
The apartment is lovely, with comfy bed, where we really felt at home. There is a kitchen with everything you need, and a comfortable shower with hot water any time.
The WIFI was working properly the whole time, and we used it happily !
Though we didn't meet Tolga,(got the keys from his friend Orion who was lovely!) he was always generous and asked if we needed anything, and was always available for questions.
To sum up, we're going back to Istanbul, and we're gonna sleep at Tolga's place again.
