The location is great. You have everything you need around: shops, nice food and sights. The only problem might be that you have to climb up and down the street - it’s steep. But it’s Istanbul, so it’s very common.
The apartment has everything you need. Beautiful plates, glasses, forks etc so you can wine&dine in a beautiful atmosphere there.
The bed isn’t comfortable to sleep (my personal opinion), the shower is too small and water pressure isn’t good enough. It also was quite cold so I wouldn’t recommend to stay there in winter. It’s perfect for spring, I’d say.
Dilek is a wonderful host. She helped us a lot!
