The flat was clean and well presented with a welcome basket and met our needs for 6 people very well. It appears as pictured.
The position in Beyoglu is within walking distance of the tram and the Galata Tower.
There was daytime noise from building next door but this did not start until around 1000.
Berk was readily available for help with queries-( the transport offered by Berk from the airport is worth considering especially if you have a number of people with bags).
We would certainly stay again if we come to Istanbul again.
