We had a wonderful time in Terri's place. It is located in a great spot, close to lots of restaurants, cafes, bars - the best little cafe for a great dinner is Imbiss 204 at Prenzlauer Allee 204 - great food at a very reasonable price.
We were 2 adults and 4 children (ages 10 to 15) and the apartment was more than adequate for us. It was great having two, wonderfully renovated, bathrooms. The kitchen has everything you need. The apartment is very well heated.
There are a few stairs, which didn't bother us in the slightest but would not be great for anyone who has difficulty walking.
Terri was very prompt in communicating with us. Thanks for everything!
