We had a nice welcome from the host and he showed us everything .
It's a very comfortable flat and worth the money .
There is a pedestrianised district about 5-10 mins walk away . And you have lights and many shops . This leads to Galata Tower and you can then take the bridge and eventually get to Blue Mosque and Hagia Sophia plus Topkapi . Maybe it's better to take the tram though as it can be tiring walking around all day but you see a lot more of Istanbul .
I would recommend this place
