Tours in Azerbaijan

Hi all, I'll be travelling to Azerbaijan this February and I was told by someone online that booking a tour through Tripsome website would be good. Has anyone tried booking their Gabala tour through that app? It is way cheaper than other websites but the lack of reviews makes me quite hesitant to use the app. Here's the link to the tour: https://tripsome.az/en/activities/05d568/gabala-and-shamakhi-tour

Any insights would be highly appreciated!
