Reviews for Nepal High Trek?

I’m looking to go to Nepal this spring and do the Langtang Valley trek. It is a solo trip and I’m 26F so safety/comfort are very important to me! I’m looking at using this company to take me on the trek: https://www.nepalhightrek.com/activities/langtang-valley-trek/

I’m wondering if anyone has any experiences with this company, or others? Thank you in advance!
