I think being in the same building as SPs would be a bad idea for you and the SPs. You and the SPs both want discretion and not to bump into SPs or SSs in the place they're living. Living in the same building as SPs would get awkward and I suspect the SPs wouldn't see you if you told them you were in the same building as things could get nssty if you had a falling out with an SP. My advice is don't do it.
TBH as an SP I find this a bit creepy, we try and stay as discreet as possible when I book and use apartments, I don't even share the information of where I stay with other escorts (other than one close friend) if I find somewhere that is workable and in a nice area as I don't want it to get overused and become unworkable.
Giving that kind of information to a SS who wants to be in the same building is an absolute no no for me, just do like we do and do your research on the kind of apartment you want to stay in and then do a local search for someone who ticks your boxes and book them.
I've had guys tell me they are in the same hotel and I find that creepy, it could be management trying to trick us etc, there is absolutely no need to even tell an escort that kind of thing, just book and turn up we don't need or want to know if you are in the same building, unnerving to say the least.
