Elizabeth's son met us at the apartment. He explained the elevator and the house situation. The neighborhood was easy to walk in and around. It is a lengthy walk from the house to the train station, just something to keep in mind if you have large luggage. We had a pleasant 2 day stay at Elizabeth's. I would recommend staying with her. Our first morning we were dealing with jet lag and slept very late. Elizabeth accommodated our tardiness and the house was so quiet that even while everyone else got on about their day we did not hear anything.
The only adverse side was that there were 2 of us in the room and the 2nd bed is a trundle, which made it difficult to get in and out of the room when the second person is sleeping.
