Bernardo was great, was prompt and informative, helped us know our way around the neighborhood. The apartment is very simple, nothing luxurious but the beds were comfortable and everything worked. There is a comfortable courtyard garden for relaxing outside. We loved Kreutzberg, took advantage of the Turkish market which had all kinds of lavashly delicious food, as well as being great for people watching.
Sadly, my mother tripped and fell on the cobblestones and dislocated her shoulder while we were here. It was too bad but made us feel great about the neighborhood because everyone in the street stopped to care for her and the paramedics and hospital (4 blocks away!) were absolutely top notch.
I must warn people that the street is noisy, so bring earplugs in summer.
I definitely recommend this apartment and host.
