We have just moved to Zurich and decided to stay with Joy after a great experience staying at one of her apartments previously. It was our first time in Castle Neumünster. We had a fantastic time. The only reason we left was to move to a different one of Joy's units for a longer term stay.
As before, the apartment was clean, usable, generously supplied, it had everything we needed to do our own laundry and prepare our own meals (after a trip to the grocery store, which is a short walk or a single stop on the tram). Joy responds quickly and clearly, and demonstrated care that we have a good stay as her guests.
The public transit connections are great - the tram and bus stops are a 2 minute walk away. The stairs gave us some exercise, and the wood floors are creaky, but neither was a problem for us. There are multiple playgrounds in the immediate neighborhood, which was great for our kids, as well as a grassy field which our dog loves.
Joy was able to arrange the form I needed to register at this address. I strongly recommend her as a host in general and this specific unit as well.
