No - because there isn't "just one" sea view unless there's just one room overlooking the sea. By starting the sentence "I'd like a room..." you are presuming there are a number of rooms like that - and each one will have a slightly different view depending on it's position. So there is not one sea view from the hotel, but lots of different ones depending on whether you are on the first or tenth floor, the left of the building or the right. So what you are saying is "I'd like a room (it doesn't matter which one) with a sea view( it doesn't matter which one). Only if there was only one room overlooking the sea (and therefore only one view) could you say "I'd like the room with the sea view."
