We loved our rooftop stay at Simon's and found him and M'lou to be good hosts. The apartment was bright, clean, nicely decorated and satisfactorily equipped...(even some spices in the cupboard). Having to pay extra for air conditioning was not so great as it was hot on the roof and the temperature in the apartment rarely got below 25. I do understand that people can be wasteful but perhaps a way of ensuring it is switched off when you are not in the apartment would avoid that. Simon's Pub below is funky and worth visiting for a drink to check out the ambience.
