Iris was away while I stayed in the apartment but her co-host, Terry, was very nice and welcomed me in. And even though she was gone, Iris still checked in on me.
Two other people lived in the apartment but everyone was very respectful of the others' privacy, so living with them was very harmonious. The apartment itself is very clean and has a lovely terrace, although since it was winter I didn't use it much. It was smaller than I expected but in no means is this negative. The apartment is very cozy.
You can hear the train at night but for me this wasn't a problem as I read previous reviews and brought earplugs.
