I would very much recommend this! Natalia is super friendly, the apartment is (although on the 5th floor - no elevator) clean, quiet (im 'Hinterhof'), cozy, has more than enough space for two adults and two children. The apartment is located in a quiet neighborhood, which does require public transport to get anywhere (but this was not a problem, bus and metro-stops are around the corner). There is a supermarket within walking distance. Thanks Natalia!
