The ease of use, great support team who are always willing to answer any questions you have - we've used them as our PWA provider since 2014 which has been without issue so far! We're looking forward to their integration with Zapier this year but other than that there's nothing I dislike about working through Hotelscruz (or even using it in general). Their customer service was lacking during my first contact when they were just starting up at one point though now all seems well again :) Greatβ¦
