Amit's place is hiper cool. The list is long: great location, cozy, clean, quiet (we were there during the soccer game between France and Germany UEFA 2016), well equipped, and so on.
Even tough we couldn't meet Amit in person, he was very helpful, and made sure that everything was in place for our arrival, and kept excellent communication with us all the time.
Berlin, in general, it's an incredible place. Amit's apartment made us feel a part of it.
