Unfortunately, I had to cancel after the first night of a 7 day stay due to a cockroach problem and bad smell. It was very warm in the apartment and poorly ventilated which might explain these issues. I messaged Johan about this when I checked in at 8pm and received a reply at 13:45 the next day, by which stage I had already checked out. Johan refunded me for the cancelled nights and an additional refund to cover most of the first night.
The apartment has a good quality king size bed, work desk and chair as well as good linen. However, the sofa and rug are are both very badly worn and damaged and not at all in line with the 'High-End' description.
All in all, this was a very unpleasant experience for me which left me having to look for somewhere else to stay.
