We had a pleasant stay in Murat's apartment for 12 days and felt like home. The apartment has 1 bedroom with double bed, wardrobe and two balconies, and 1 bedroom with two separate beds, one balcony, wardrobe and big kitchen table for 4.
We found really comfortable beds, kitchen with all necessary amenities, including coffee machine, big refrigerator. Istanbul is a little bit noisy, but that noise didn't affect our sleep.
The apartment is located about 7-10 minutes walk up to Grand Bazar and Tram, 4 minutes down to the sea, and 15 minutes to the Blue Mosque. Also, there are 2 supermarkets near the apartment (Bim and SOK). Opposite the building we found the street with a lot of restaurants.
Thanks, Murat, the apartment is recommended!
