When we stay in rented apartments or cottages I have always found if there is anything broken or missing the management company or owners will sort it out for you if you ask them.
As the owner of a guest house I prefer that guests speak to me if there is anything they want sorting or they are not happy about, as it is always best to keep the customers happy than get a bad review.
Luckily we have very good reviews, but if you get bad ones it can really hurt your ratings.
Anger management!!! Help needed.
