I stayed with a party of 6 in this apartment, it was great and the host was even greater. The apartment is just like in the pictures (or even nicer), it is beautifully decorated, clean and FULLY equipped. The beads are really comfortable, and everything worked perfectly. On top of this our refrigerator was filled with bottled water and soda, we had coffee machines and ground coffee beans (Turkish and drip), sugar, salt, pepper,oil, etc; we had soap and shampoo in the bathroom, all included. Barbaros is an amazing host that waited us with (courtesy) breakfast when we arrived at 4:30 am after our plane got really delayed. This tells a lot about the person, one week before we were charged 30 euros for arriving half an hour late to pickup the keys for an apartment in Paris; but this guy waits for us 5 extra hours and gets us breakfast!!!!!! Aside from this he was very kind to give us some guidance, he called to check that everything was OK and came to help with the washing machine (it's in Turkish so I didn't get how to use it).
The location of the apartment is good, you're at walking distance from almost all tourist attractions in Istanbul; there is also a supermarket, pharmacy and other shops around. Four blocks away there are some nice restaurants that are a must.... Barbaros has a restaurant there which is very nice and food is delicious (I had the best fish ever), he sat down with us and shared a bit of Turkish culture, politics and religion, we had a great evening there. The nearest bus stop is 6 blocks away and tram is around 8 blocks away. We used mostly taxis which are cheap and you can just take them in front of the apartment. I would compare this with a 4 stars hotel for the quality of the place and the service but it has more to it, it feels a bit like home or staying at a friends house.
