The Small Guest Room is the cheapest guest room for guests to rent in Strangetown Hotel in The Sims 2. It has a base value (price per night) of 400 simoleons. It is very compact and it fits less than ten large items, rather than the limited fourteen items.
It is already built when the player starts the game and is the smallest of the four guest rooms leading off the 2nd Floor Lobby. It is a bit of a mess with the wallpaper, but it's the first room to occupy the guests when the game is started and none of the guests complain about it, unless it is a mess or has missing items.
