Nestori laughed. "I'd say from three days to a week worth of learning about this city, Sebastian's job, movements and impersonating your characters before starting to break in homes or impersonate people?" He said to the lot, looking bit around the hotel lounge in case of someone was listening. They were in no hurry, so he indeed wished to know if the house would be completely empty of people when Sebastian left the place. To pick up places to escape into if things got too rough and finding something to wear in this city to not look too distinct from other people. Furthermore, he wanted to practice his lockpicking skills before getting in action. 

And to be fair, it was a good Hotel they were in. Hell, he hasn't really been in hotels before today. Nestori wanted to have his share of experience about such place where the rich people would stay. He enjoyed the local beer he had ordered for himself, the care people took from his luggage and the service in place overall. This he would call life if he was a businessman! But then again, the countryside had it's own comfortable side. And besides, owning a forest, fields and house was less restricting to the hotel room he was offered. He imagined that the loan of the farm and animals and few other troubles would settle down quite well when the payment from this job would come.
