We had a great stay in Alan & Kasia's place. They were very helpful and Alan was on hand to help us get to the apartment from the central station during check in. The room was clean and had a fan for when it got warm. Local maps and guide books were available to help orientate ourselves within the city.

The apartment itself is very conveniently connected to the central city via a tram stop and the local neighbourhood is great with shops, post offices and cafes. Although I recommend using the tram to get to Alexanderplatz and then walking to the centre, the entire journey is possible walking. However I do recommend not doing this at 5am after a night out in a Berlin techno club...
