I do know what she means....
Down at the cheaper end of the booking dot com listings you can find quite a few accommodation options that are a little evasive about what they actually are. More places advertising themselves as "guest houses", when what they actually are are shared properties with various rooms rented out, a key code to get in and no staff on the premises.
But you can avoid these places with a bit of common sense and by reading the reviews thoroughly.
I have used booking dot com a lot, and have had one dodgy experience, which I think was an Italian accommodation provider trying to pull a fast one. Guess what, I'd skimmed over the fact that the place only had one review- and that a suspiciously gushing one!
If you want a proper reception (which is a fair request), only book with a hotel that has a physical photo of the reception, cross referenced with reviews that say something like "Great service at reception!"
Otherwise, I recommend the Rough Guides and the now- defunct Cadogan Guides for giving you the flavour of a place and for fresh ideas on where to go. I think their hotel recommendation pages are rapidly becoming obsolete though- the information will never be as current as what you can find online.
Although I'm a Luddite, I have found Google Maps great for a) finding cheap campsites, and b) showing attractions I may not have thought of. You can be browsing an area and have the most unexpected things pop up! It's how I found the Voodoo Museum in Strasbourg for example, which was excellent.
Searching the Guardian's old travel articles can be good.
Seconding The Man in Seat 61 if you're travelling by train.
