Lena's apartment is a great place to stay in Berlin. The area has a lot of lovely bars and restaurants. The apartment is very quiet and had everything we needed.
It is very close (<2 minute walk) to Gneisenaustraße metro station, from where it is easy to get to anywhere in Berlin.
I recommend a visit to the Ramones Museum and to see Hertha Berlin play at the Olympic Stadium.
Lena was very helpful and clear in all communications.
This apartment is a great base for anyone looking to stay in Berlin.
Thanks Lena
