First of all, Berk's place is the best choice anyone should book. It is very cozy, clean and quite, well decorated with a soft relaxing colors, sunny at the day, you are home.
Berk is a good example of a super host, he will let you feel free to be yourself and enjoy staying for a warm cozy night as much as expericing Istanbul itself.
The room was a little bit small for two persons with too much luggage, however, thats not a problem given the comfy stay in general.
Everything was superb
Thank you Berk
