The young man who greeted us was very friendly, and the bikes were convenient to pick up directly from the property.
The only downside concerned our reservation. We had reserved five bikes the day before, including theft insurance. In the morning, one of the people couldn't show up. The young man asked his manager if it was possible to get a refund for that bike, but the answer was no, on the grounds that no refund was possible, as stated in the contract.
However, this contract wasn't explained to us: we were simply asked to sign at the bottom of the page, without any mention of this clause.
It's a shame, especially since we are among the owners of the property. A gesture of goodwill would have been appreciated in this situation.
