The location was the best for us. It was really convenient. I grew up a block from this apartment and bringing my son and showing him around was great. The place is very well decorated for just a vacation home. The host was very helpful and available all the time. The hot water was a problem for us, it kept changing the temperature on us while showering so the owners needs to fix it. We also wish there was a fan in the apartment since it gets really hot.
If you want to stay in the heart of Istanbul without paying a lot of money I would definitely recommend this place.
