Great location for getting to the main sights and a very short walk to the U+S Bahn as well as bus stop. Very quick and easy to the airport, and Volker's instruction are very helpful.
Apartment is great (me and two of my kids, would be fine for 2 couple - but I'd suggest for just a few days.
Although there are busier areas for bars and restaurants (around the Zoo for example) there are a number of hidden gems within 15 mins walk - you just need to do a bit of homework.
Do bring earplugs if you're not use to noise (we live on a farm!) and sleeping in the front room!
Loads of little extras which were deeply appreciated.
Only negative was the broadband which went down the first morning and was never restored - it got expensive for us after we blew our data plans.
