I highly recommend Lisa's apartment. It has a perfect location, near to the train station and the old city(where one should not ignore as a tourist), thus one can easily reach everywhere in Munich. Plus, there are many restaurants and bakers around the apartment. The apartment itself is very clean and cozy. The kitchen is well equipped, the TV and audio system also work good, there is even a mini gym at the balcony. Lisa and Amad offered a good guide and they are both very nice and helpful.
In all, as a tourist, I strongly suggest that you choose this apartment to start your exploring in Munich.
