Simone's apartment was beautiful, clean, and in the perfect location. The pictures don't nearly do it justice, it really is fantastic! Simone was kind and easy to communicate with. Check in was as easy as it gets. With a 5 minute walk from the train station, it is also very easy to reach. The apartment felt safe and secure, and we were all very happy with the experience.
One thing to note-- the bedroom with two twins in it was perfectly quiet. The two other bedrooms do face a busy thoroughfare so occasionally we could hear people talking or rolling suitcases by (even when windows were closed). I would just be sure that you do not put light sleepers in either of those two rooms. My group didn't have any problems once we had fallen asleep! My mom, who is a light sleeper, stayed in the quieter room.
