We got upgraded to a different (larger) apartment than the one we booked due to a technical issue. Where we stayed was very well located on a small side street just 3 buildings from Galip Dede Cad. and <100m from Galata Tower. Due to the location it can be noisy at night, we expected this but if you're sound sensitive bring ear plugs. The apartment we stayed in was lovely and had a lot of historic charm, the only downside was the internet which was so slow it was unusable (tested at 15mb but couldn't search for location in maps or even check your email.). The kitchen was well equipped with a dishwasher and laundry machine but no laundry soap was included, so BYO.
