1.I like to live in homestay. (period need here) I like a room with wifi and a sea view. If there were a fridge and a closet in the room，it would be perfect. 2.I prefer homestays to hotels，because the rooms in homestays are always more personal. "individual" doesn't make sense. I'm not really sure what you meant to say. I guessed that you meant "personal" but I don't really know. If you describe what meaning you had in mind, I can give you a good word.
