Specific requests are noted but not guaranteed. If you really want a certain room, you are limiting yourself greatly in getting the request.
I'd suggest requesting a certain view or group of buildings, but would discourage getting too specific. It could happen, but more likely won't. Calling day by day won't really help with that type of request. since they might give that room to someone checking in a day or two before you- even if they reserve later.
You can certainly make the request, but I'd add other requests (like view, floor and buildings) to improve the chance of getting something. Otherwise, they won't really know what you're looking for if the specific room isn't available for your arrival.
Good Luck.
