The house was old but really nice with beautiful touch. Close to Galata tower and good location(easy to get a bus)
The only thing, It's hard to go with luggage since there were many stairs. I had issue with taxi driver because of the road. If you have heavy luggage (suitcase I mean) it's better to take another road.
Michel was amazing host. He gave me good advise and useful tip for my journey! (He even wasn't in Istanbul that time.) I will never forget the beautiful sunset view from the rooftop. Thank you Michel!
