The price / performance ratio doesn't fit at all. Just like the customer service that we contacted at the holiday destination. The apartment was full of defects, e.g. the cellar was under water, some of which were repaired by the local master builder, but that was only a drop in the ocean. I've been waiting for a response from TUI Wolters since the beginning of July.
Very customer unfriendly. That's why I would prefer not to give a star.
But this was the first and last booking via Wolters.
