Escort in Prague / Inviting call girls - Czech culture

Hi, I would like to know what precautions I need to take while calling the girl to my apartment. I need to go downstairs to pick the girl as I can't open the main door from my flat. Till then she has to wait near the main door. What do other Czechs, mainly families staying in the same apartment think? Do they bother and try to stop me from inviting girls or just ignore?
