Dominic's apartment is an excellent base from which to explore Berlin. The neighbourhood is very interesting (both for its past and its present) and as central as you can get in this polycentric city (and we know, having formerly lived there ourselves). The apartment itself is spacious, stylishly furnished, thoughtfully equipped with everything you need, and easily accommodates up to 4 persons (we were 3, and used the sofa in the living-room as a second bed). And if you plan on being sick in Berlin ;-), as we were, it is ideal: the beds are comfortable, the bedoom is very quiet, and essential shops and a pharmacy are only a few steps away. We did not meet Dominic, but communication with Ida was swift and efficient. Highly recommended.
