It was my first time visiting İstanbul. I wouldn't stay in Fatih during my next visit. Barbaros' place is a nice place if you want to be walking distance from touristic attractions. It is next to Ottoman Park Hotel.
If you have a car, finding parking is a little tricky in Fatih. There are some guys who manage the parking lot by the hotel and across the street. I had a rental car. The lady who helped me check in referred me to these guys. They told me they charge 15 Euro a night. They tend to overcharge you if they know you are a tourist. These guys fill up the whole area, including the spot, which is supposed to be the loading and uloading area for Barbarose' place with cars. On the check-out day, I had a hard time loading my luggage to the car. The parking lot guys were very rude and unfriendly because I had to park my car in their parking lot for 5 min. Even though they had blocked loading and unloading area. I found another parking lot nearby for $3 a night during my stay.
