The apartment was beautifully designed, very cosy and spacious. The location is very good as its just off the main high street road. The Galata tower is within a 15 min or so walking distance (you may need to climb uphill down some side roads).
As you will be near the main road there are also many small shops on the opposite side to the main road as well as a taxi stand, and a tram station about another 15 minutes walk (you can take the tram directly to the main attractions on the other side of Istanbul for 15 Lira).
Apartment comes with the usual amenities you can expect. Irem was very helpful, any queries we had we could just whatsapp her and she would always help. She made us feel very welcome in Istanbul and we would stay here again if we visited once more.
