Response from Claire:
Effectively I explained Kamilla that the water goes down a little slowly but there is no problem to use the shower and the sink. I use it twice by day with my family. But because I explained her that, she thought the system didn't work and didn't ask me to repair the shower during the location. But effectively there was a specific problem that I discovered after they left (because she said to me at this moment unfortunately) and I made it repaired immediately. That' s because a bad communication. That's ashame. Say immediately if there is something wrong in the flat. I do my best to receive people.
