Really cool studio flat in a GREAT location with AMAZING views of the city and also of the famous TV tower. Everything was clean and functional, the flat has really cool touches, it's quiet enough with the windows closed, and that view - wow! Fans of time-lapse photography take note! As far as the location: you're a 2-5 minute walk from Hackescher Markt and 5-10 minutes from Alexanderplatz, which puts you in the center of the cool shopping district as well as close to super great food and all the major transportation services the city has to offer. Food tip: try Madami for amazing Vietnamese just a short walk from the building.
I highly recommend this place for single travelers and for uncomplicated couples (it's a single room, but not cramped).
Oh and a final tip about WiFi: the connection was fast and reliable but sometimes I had to toggle WiFi on and off again after my laptop woke up from sleep. Could be a Mac thing or could be the router --- either way take note, if the WiFi seems "stuck" just disconnect and reconnect again and everything is fine.
