Dunapart Hotel, Budapest

If you're looking for a unique Budapest hotel experience, then you won't go wrong with the Dunapart. It is in fact a permanently moored boat on the River Danube, almost directly across from the parliament buildings. The rooms are the actual ship's cabins, with the same style of beds and the same rather confined space. It is definitely worth a look. The boat is within an easy walk of many sights and of course the Danube is right outside the window.
