Small appartment in a very central location. Facing the backyard its also really quite for an accomodation right in the city center (Don't leave the window open all day, the kitchen of the restaurant goes to the backyard next to the terrace and it may smell - its italien kitchen and I liked it, but maybe not for everybody).
Its well equiped and I didn't miss anything during my 3-day stay (even a deep freezer is available). Bring some Nespresso Capsules and you can use the Coffeemaker in the morning. I recommend this studio for 1-2 persons and would come back when visiting Den Haag !
