I started out under the staircase and I had to be a little bit careful coming out because there are guards walking around so as soon as the one guard, who walks his circuit around the area at the bottom of the staircase, walked by I came out and went to the right and jumped over the cabinet and the railing and then quickly changed back to the present.
The swimming pool downstairs has a number of nests but no nest keepers so you can just take them out with the sword and collect all the nectar.
Upstairs there are a number of nests and 2 nest keepers. I choked out one and the other I used a sleep dart . Once the nest keepers are taken care of you can explore and collect all the loot.
Thanks for watching
