We are sorry and will take you remarks to improve guest experience.
As far as the water , here is the technical situation. As you wrote it, it is practically impossible to find a plumber immediately on a Friday night.
The plumber came at 9am on Saturday morning. You will agree that it is a very short delay.
Had you stayed some more nights, the problem would have only lasted during this night.
The water was only coming out when the sink or shower was used. It was a great inconvenience for your last night but there was possibility of using the water in the sink.
The plumber found that the pipes were obstructed by food scraps thrown in the sink. In France, one must not throw food scraps in a sink, they are not equipped for this use.
We are sorry you found our answer was not at the level it should be. We have talked to our employe to ensure the explanations should be more service oriented.
We try to learn about issues like this and will do our best to improve the guests experience.
Hopefully we have many reviews which show guests in majority appreciate our service.
