The stay at Murat's place was amazing. His brother Ali is in charge of the house, everything is clean, in order and kitchen is fully equiped. Bedroom is spacious, great for a solo traveller or even for a couple. As Ali is vegan, it will be better if you don't cook meat in the house.
Something else: location and neighbourhood are perfect, close to ferry for going to Suktanahmet in 40 minutes and chill neighborhood, calmed at night and full of cafes, restaurants and everything you may need.
