The apartment was in the perfect location near Muzeum, but far enough away to be very quiet at night. They were very responsive and helpful.
There is no ac, which made our first night a bit difficult in the heat wave that only cooled down to 90F (32C) at bedtime. However, Alex and Kate did bring us a fan on the first day, and two more on the second. Additionally, we could not seem to get the internet to work.
Altogether, our stay was great and I would recommend staying there!
