This is an overestimated and overrated places I have stayed in, in my trip to Turkey. For location, it is perfect with the fact that many of the best rated restaurants are down the corner, and the place is very close to the key attractions in Istanbul, including Fateh and SultanAhmet areas.
However,
1/ the listed location does not match the real location. We have parked in the area as mentioned in the address and discovered that the property is located some 500 meters in an up hilly location. Mr. Hekmet and his friend helped in moving our luggage to the place, but we have suffered for three days going up and down.
2/ It is neither 'stylish' nor 'one bedroom apartment' as described. It is one bedroom, a very small living room with a sofa, and a small basic kitchen with old electric equipment.
3/ For families, or guests with children, try to avoid this place as the stairs itself is a nightmare.
4/ The noise in the property from outside is unbearable and it continues until late at night. A very busy shoe shops and mini-factories are along the street and the adjacent streets. People keep talking and shouting until late night. As we were offered the first floor, the noise was as if we were staying in the street.
5/ We've never used the kitchen for anything, despite the fact that we were in need to make some food and milk to our kid. The kitchen is so simple, and the inside atmosphere -all in all- was negative.
6/ the washing machine is in the terrace, which is in the 5th floor of the building, making it not part of this 'apartment' and logistically difficult to use for those hosted in the 1st and 2nd floors.
7/ The host needs to do much improvements to the property: the TV has a very small screen and hanged mostly as a decoration without being connected to WiFi, the bathing set is too old and barely making out water, the wooden items are too old and does not fit.
All this does not subsidize the reality that Mr. Hekmat was super welcoming, supportive, and good communicator.
Lastly, I do not recommend this place for families, and it's not worthy of the pay.
