Great place to stay in south-east Fatih. Ahmet (owner) is very hospitable, rooms are clean, albeit very modest. Someone was 24/7 available at reception. Host was willing and able to help with any day-to-day problems, like where to buy, where to repair the phone (he was able to find good price for me).
Place has great view to Murmur sea and Prince' Islands. It is literally 5 mins from Blue mosque and Sofia.
Some rooms (or all, not sure, at least mine did), had basic gas stove to cook and fridge. There was a shared laundry machine.
While I definitely recommend the place, it might not be for everyone. Region has late working restaurants, so that, despite Ahmet's efforts, there was some late noise weekends' night. This might be true for most hotels in the area.
Overall, everything is very simple, friendly and personal; if you are looking for five-star hotel, and formal service, this might not be for you. This is family business, not internation brand.
Overall, I am giving five stars without any hesitations.
