We loved our stay in this apartment. The location is so close to the Galata Tower which is always full of life but tucked away on a more quiet street so you can get rest. The building is old but decorated with charm. If you are not good with stairs just be aware you will have to go slow entering and exiting.
It was comfortable and good bathroom and washing machine with supplies included. The biggest help was the hosts being so accomodating when asking for assistance and communication was prompt and clear.
