The flat is very nice and has an amazing location. You have to walk 5 minutes to reach Istiklal street and nearly 15 minutes to Eminönü. The next Metrostation is 5 minutes away. Location is a 10/10.
The flat is well suited for 4 people, if one person sleeps on the sofa. If you dont need expensive things, this flat may be your best choice.
The Hamam and Sauna are of course the main selling point. After a long day in Istanbul these were well seen by all of us. Sadly the hamam was broken on a few days of our trip.
