I actually stayed at casa luna in May 2010 but have been wondering all these years if if was still around. I'm glad to see that it is because Mario is a gem. He is honest and will help you out wherever he can. I was in Antigua for almost 2 weeks and Mario's place was affordable, clean and well located. He organised some transportation for us and was just a great guy to chat to. Loved Antigua and would highly recommend casa luna to any traveller looking for great hospitality.
