You live 13 minutes by walk from buses and ferry station which can save you from wasting your time in the bloody crowded in European side
They can take the ferry each day to get to the historical place of either Faith or Galata side without bothering yourself living in that area. But keep in mind that with Istanbul cart, the rate of tickets for taking the Ferry would be halted.
By booking this apartment you have less than 5 minutes to 3 adorable coffee shops nearby and plenty of grocery stores and Boulanger (bakery).
We were 4, and we have spent amazing moment exploring eastern side of Istanbul in the first floor of this astonishing apartment
Seyma accepted to deliver the keys to me while we had hours to check - in due to my last minute ticket's changes, and she also helped me with baggage to be taken to the first floors (at least 12 stairs a re waiting for you)
All in all you would love spending your time in Eastern part of Istanbul, I would say don't forget to visit Baghdad Street and its nice and lovely cafés and restaurants
