We are happy you enjoyed your stay and i'm so sorry to hear about the dogs. We never had guest mentioning it until last month, you are the second guests who did, so I wonder if it's some new dogs in the area who just moved in lately or other people were not so bothered. As you said unfortunately it's not in our power to change the barking dogs problem, ad as we don't live nearby we don't know how bad and often it is either... But I have just updated our Casa Aloha description of the neighborhood and mentioned about this issue so other people know. I hope it's temporary.
As a dog owners ourselves we are very upset how some people around treat their pets, just keeping them outdoors all the time and not giving them enough attention. A happy dog wouldn't bark all night..
