Lena's flat is very nice, well decorated and very well located. The bed is comfortable and the kitchen is well equipped.
We spent 4 nights in the apartment and enjoyed the lively neighborhood and the nearby metro station which allowed us to visit everything we wanted easily.
It was perfect for a couple with a baby.
Lena was very welcoming and available. We did not meet but the key exchange was very easy.
I have already recommended the apartment to friends who would like to discover Berlin!
