I can not recommend this Riad and it does for sure not deserve the superb rating. Just after booking i got an email asking for cash payment on arrival, a lot of text in big printed letters, what can be expected and what not *as there is no cheese in Morocco&* for example. Not very inviting and not also not corresponding to the text< book now, you will be charged by booking out.
I pay the invoice and got only a hand written invoice, not even the name of the Riad Balthazar was printed. The usual cards with a map of the place are not existing, even if the place is not easy to be found, especially not in the night, as a portal door is closed after dinner. It happend also more then once to me as well as to other guests that we had to wait at least 10 minutes in the night until the young man who should stay in the Riad to open the door finally heard the repeatedly ringing of the door bell, as he was in a house next door.
The very positive point in Riad Balthazar, apart of the lovely building as it self, is the manager, Nadja, who gave her best to make up for the disappointing fact, that not all room are air conditioned, despite the description on hotels.com. and with a temperature of 48Celsius in July this is a serious issue. After consulting per telephone the owners, two sisters living in Paris, i was offered an other room but had to pay extra 5 Euros per day. I was guest in the Riad Carina and the Riad Diana as well and can not understand the rating in relation to these other two Riads. The difference is huge.
I made some suggestions before leaving, that for example a welcome tea would be nice, as it is usual all over Marrakech. I would not get back to this Riad again and think that the text of all rooms are air conditioned is a serious offence and should be corrected.
