Safehouses in GTA V

Safehouses have appeared in most GTA games. Little so far is known about what the safehouses in Grand Theft Auto V will be like whether you will sleep in a bed to save your game like in Grand Theft Auto IV and whether you will once again save your Vehicles in Garages like in all the other GTA's before GTA IV.

Locations
So far only 3 possible Safehouses are known of in GTA V. These are, Michaels' mansion, containing several sports cars, a private tennis court and golf course, Trevors' trailer in Blaine County and Franklins' safehouse in South Los Santos. Safehouses in GTA V should hopefully contain much more things to do inside them, like maybe somewhere where Franklin can look after his dog or a place where Trevor can take out his anger without actually hurting someone (yep, that's not very possible, I know).
