I think the key is simply to walk in pretending to be on the phone, confidently walking to the stairs / lift. There are perhaps ten hotels in my home City that I've visited, never had a problem.
Apartments are obviously better in terms of linen, towels, etc. Plus no cleaners in the corridor! There are thousands of apartments here too so I guess we are spoilt for choice. Separated three years ago and fast becoming acquainted with all sorts of buildings I never thought I'd see the inside of!
In summary, not much difference between hotel and apartments tbh. My preference is apartment.
