It was easy to find and Lorenzo is a nice person, nice to talk to you ! you get info as you get apartment and if you need a place for a weekend in Berlin his place is your best option! location is very nice and close to everything . you have nice restaurants around to eat and so many shops around! just don't forget to have cash when you want to eat :) (as it is in Germany, people love to have cash for some reasons)
anyway i enjoyed staying there and it was nice to meet Lorenzo and his Wife! I totally recommend the place !
