I haven't finished this part yet, but you can check out the awesome work from Phasmo Team HERE
Tanglewood Drive
The guide is mostly the map on the right with all locations, so here I will just put few more information.
Tanglewood is a small map (Tanglewood and Willow are the smallest maps), it has only 2 floors (first floor and basement) and is well known because it is the tutorial map of the game.
Possible Hiding Spot info
The Possible Hiding Spot on this map is behind a chiffonier on the dinning room, you can crounch there and it's very likely that you will stay alive if the ghost haven't seen you or sensed you (so turn off your equipment before you hide there).
Best and Worst place for Ghost Room
The worst Ghost Room you may get on this map are on the Foyer and on the Living Room because those are big and can be easily confused with other places, also Utility Room is no good either, since it means the Ghost will interact other places, like Garage and Kitchen, because it has almost nothing inside the Utility Room. The best is probably Nursery, because is small, but not that small and is easier to get evidence.
More info
I also don't advise hiding inside the Foyer Hiding Spot on the right (close to the Living Room), the Ghost usually opens a lot that door. My favourites Hiding Spots in this map is the one in the Basement and Nursery and the Possible Hiding Spot in the Dining Room because there's no door that the Ghost can open.
Some say it is a good map for beginners, but I disagree, because if the Ghost Room is in the Foyer or Living Room it may get new player easily confused, the ghost will interact to a lot of places since those hallways are really big (if the Ghost is in the Living Room it will interact with the Hallway in front of it, where it has the door to the Basement and Utility Room).
Willow Street
Willow is the second smallest map this game has, it is one of my favourite maps, it has only first floor and basement like Tanglewood.
Possible Hiding Spot info
The Possible Hiding Spots on this map are, behind the tool desk in the Garage (I died on this spot a few times, but I still usually hide there) and behind the desk inside the Master Bedroom (also not very reliable).
Best and Worst place for Ghost Room
The worst place for Ghost Room you may get is the Basement Hallway, because it's really big, Garage is no good either. The best is probably the Bathroom or kitchen, they are small, easy to get evidence, easy to use crucifixes and there are a lot of stuff for the Ghost to interact with. The rooms in Basement might be good to for the same reason, but it's scarier to stay there.
Grafton Farmhouse
Grafton is an awesome map, it is scary and has the most Possible Hiding Spots quantity meaning it is a good map to try a 'No Hiding Spot run'.
Possible Hiding Spots
My favourite one is behind the couch on the second floor (just upstairs and right).
The second one is behind a cradle inside the Nursery (room upstairs on the left).
And the third one is besides the fridge in the Kitchen.
Best and Worst place for Ghost Room
The worst place is in the Living Room, it has so much space, it's hard to get D.O.T.S and to use crucifixes. Also, Master Bedroom and Twins bedroom are bad, because it counts the bathroom as the same room so also hard to get D.O.T.S.
The best place is Storage(Workshop), small, but not that small and it is close to the Kitchen where you can loop the Ghost.
Edgefield Road
Edgefield Road is one of the medium houses the games has to offer, it is medium, but it doesn't have much space, it is one of the most hated houses and I agree, I dislike it too.
Possible Hiding Spot
The Possible Hiding Spot here is besides the table in the Dining Room, it doesn't work very often, but if you have nowhere else to go, it's a good spot.
Best and Worst place for Ghost Room
Upstairs Hallway is probably the worst, it is really big and has a lot of walls making it harder to find D.O.T.S.
The best in my opinion is any room upstair.
