Everything went well, the host is super responsive and very kind.
I just have to point out that it is good to save water for the environment yet the water heater is relatively small and the hot water finishes just about at 5 min of a normal shower.
Also to point out the heating at the lower level of the duplex that is quite weak and with 2 degrees outside it doesn’t warm up much. It was on for a few hours but not much impact.
For the rest, great location, great host and enjoyed my stay for work in Brussels
