We were four friends (all guys) staying at Emirhans apartment for 5 nights.
The location was really good, close to the tram and metro stations and short walks to Taksim and Besiktas where you'll find many restaurants and very good vibes both during the day or night.
The apartment was very spacious and comfortable, good aircon in all rooms, nice kitchen area. There are fantastic views too as we were on the top floor. Tuna was also on hand via a phone call if we needed anything

Overall our stay was excellent, definitely recommend this place. And if I return to Istanbul I'll stay here again.
