I stayed there for one week and would do again!
Although Karl and Catherine threw a party on my day of arrival, Karl took the time to show me the flat, bathroom and kitchen and explained everything. I got the chance to taste a Kopi Luwak. Thanks for that!
Conclusion:
Very nice hosts, great location, spacious room with a private bathroom (fully equipped shampoo, shower gel, body milk, towels, etc)
I recommend the Jacuzzi Suite with a clear conscience!
