Lena was a great host, she was always available to communicate to and she answered all of our questions. She was very responsive when we were having trouble realizing that in Europe compared to America the 1st floor was actually the 2nd floor if you are from the states. Her flat clean and in a perfect location. We were able to experience the younger professional lifestyles without being immersed by other tourists. Her flat was located very close to the metro and it was easy to get to anywhere within the city. We love our stay in Berlin, and Lena helped us make an enjoyably unique experience.
