We have just returned from a week at Casena Mongerrati. My whole family is completely exhausted as we couldn't sleep last night due to an 18th birthday party being hosted at the Casena Mongerrati until the early hours of this morning! We had no advanced warning that the party was happening. We came home from the beach late afternoon, expecting a lovely quiet evening in this mountain location. Instead we noticed that they were setting up for a big party. They were expecting around 100 people. People started arriving at 9pm and the party was still going strong well after 2pm. They had a full DJ set up with extremely load music - all taking place meters away from all the guest rooms. At 2am I was desperate and went to go and ask when the party was likely to finish. They said that it might still go on for another hour. The initial response from Robertta, one main staff members was "why was I upset - our family had enjoyed 5 lovely days and this was just one evening after all". I would like suggest that one full night of the family being completely unable to sleep, is a slightly bigger issue than this. I would have been more understanding if we had been told in advance that this was happening however nothing was mentioned until we saw the party being set up and asked what was going on. I am sad to write this review because I liked so much of the rest of our time there but I have to admit that last night really ruined things for us. I feel its totally unacceptable to have paying guests put in this position. And more importantly I find it really unacceptable that we weren't told it was happening and that the staff response wasn't a lot more understanding. I will not be returning and would suggest that anyone else thinks carefully about whether this sounds like the kind of place you want to spend your time and money.
