Very good experience. I had booked the initially for 4 days but end up extending my stay for a total of 8 days.
The only thing I would suggest to the hotel administrators is to remove the useless kitchenette, which doesn't work because there is no gas and replace it with a mini-fridge.
We had to get a Styrofoam cooler to keep drinks cold.
That would be the only thing that would stop me from booking again at the Z3 hotel.
