Nope, Vendor, even your supposedly Peterbusrgish up-bringing (which your recently denounced) could not justify your pretentiousness. The word подъезд is well known in St. Pete, as a synonym of парадная or лестница. Your example "много машин припарковано незаконным образом прямо на нашем подъезде" is artificial: any native Russian speaker would say "много машин припарковано незаконным образом прямо у нашего подъезда".

The thing about прихожая is completely FUBAR. Холл the standard term for it, gimme a break.

Finally, you really ought to pay a visit to публичка and tell them you want the dictionary specifically by Ожигов. I would just like to see their faces.
