This is a great place to stay in Berlin. It is close to the airport (3 bus stops away) and close to the East Berlin attractions - (6 bus stops or a short bike ride) - like the Holocaust Memorial - or the Berlin Dome.
The apartment is quiet, light and airy, and very comfortable. It is easy to cook here, and a grocery is a couple of blocks away as is a bank to get Euros. And you can walk to the Spree - Restaurants and cafes are everywhere. Antoine is a sweet person - helping with info to and from airport, and responding to questions almost immediately. Berlin is great - bike lanes literally everywhere... and a place to rent bikes just down the street. I would definitely stay here again!
