Arthur's place is great! It's located a bit northwest of Alexanderplatz, where there are some very good cafés, bars and restaurants. Since it's near Alexanderplatz it's very easy to get to other parts of Berlin by public transport as well. The unit itself is spacious, comfy, well-equipped and has a strong, stable Wi-Fi. It also has a washing machine that can also act as a dryer. It is also in a very quiet building, so you can get your work done in peace. Communication with Arthur was friendly and prompt, check-in instructions were very precise, and check-out was flexible. Hence, I would totally recommend his apartment for exploring cool parts of Berlin!
