Staying with Nicola is a very great idea! She's very kind and helping, communicates in such nice way and helps you wherever she can. Her place is very tidy, cosy and she loves to add details to her furniture that makes you smile because it's simply lovely! The "Kiez" Zehlendorf is a good place to stay when you need to relaxe for a bit after a day in busy and amazing Berlin inner city. From the U-train station it takes you about 3 minutes to get home while you wonder thru a very interesting part of Berlin, some piece of Bauhaus architecture, very impressive! If you want to make yourself happy, stay with Nicola! Thank you, I will be back! :)
