What do you like best?
Maestro is an incredibly thorough system. Each action involves plenty of prompts, making it difficult to make mistakes. This is especially nice if you are a beginner. My first experience with any sort of property management system was with Maestro, and I will say I learned a ton.
What do you dislike?
That being said, once you've used the system for awhile, the prompts get a bit irritating. The system is almost too thorough and it slows down checkins, checkouts, transactions, etc. I also wish that when inserting notes into reservations, there's some sort of automatic timestamp/signature of the one leaving the comment.
Recommendations to others considering the product:
Learning this system will take time, but once you get the hang of it, you'll appreciate all the features it has to offer.
What problems are you solving with the product? What benefits have you realized?
Maestro's thoroughness makes it easy to avoid errors. In the instance of an error, it's easy to retrace steps to figure out what went wrong and how to fix it.
