Julian's place is in a very convenient location, close to the museums and public transport and the historic part of the city. The apartment was neat and organized well as as per the pictures we saw on the website. Julian was not present when we arrived as she was travelling and we were directed to a convenience store to pick up the keys, which is ok if you travel from the airport by taxi, but less convenient if you plan to use public transport, as it is not a walkable distance with your luggage. We enjoyed our stay in Berlin and would recommend this location.
Additional Note: There is a great deal of construction going on in the city of Berlin so a plus of this location is that the windows face the interior courtyard, the only noisy morning we had was on garbage days when the bins were emptied.
