Pokemon-go – How specific of a location can a Pokemon Lure be

So long as you are able to receive Mobile/Cellular Network Data and GPS, you should be able to wander around collecting Pokemon perfectly fine.

Also, depending on your village, there may be one or more of:

• PokeStops, which give you items like Pokeballs and Potions (and can be temporarily buffed with Pokemon Lures to attract Pokemon)
• Gyms, which can be captured, trained at and fought by members of the three Pokemon teams (Red, Blue, Yellow). You will be able to join a team at level 5.

You may be able to check this without downloading the game by using an Ingress Intel/Portal checker (as Pokemon Go is based on the same locations), however note that currently not all Ingress portals are Pokemon Go spots.

My wife had this same problem occur and fixed it by making sure that your device time was set correctly.

In her case, her device time was 4 minutes fast and not set to use network time.
