The location is so good! Close to the two big mosques and close to what happened to be my favourite restaurant I had visited in Istanbul.
Our host, Parvin, took good care of us and was very easy to communicate with.
If you need to stay in Old Istanbul, I would definitely recommend you stay here.
Note that this place arranges taxis for you from/to the airport and also provides SIM cards for use for your stay in Turkey which is very much worth it.
