A couple hours before our stay, Catherine's colleague called to inform me that the shower in the apartment that I had booked was broken but that someone was fixing it. When we arrived at the apartment we got another call that it was not possible to fix the shower unfortunately, so we were changed to another apartment (in the same street). We were a bit disappointed as the new apartment was a lot less comfortable and much more outdated and than the one we had booked initially. Catherine's colleague did tell us that we would get our money back for the first night. Luckily, we could move to the apartment we had booked the next day. Both apartments were really clean and the apartment we had booked was just like the photos. Very comfortable and nicely decorated.
Overall, we had a good experience despite the inconvenience. The communication with Catherine and her colleague was good and they tried to solve the problem the best they could. We got our money back for the first night and still enjoyed the apartment for the rest of the weekend.
