The Kulturinnov hotel is a gem, which goes pretty much unnoticed by passersby, namely because it's located inside the Hungarian Culture Foundation. The hotel is small, with only sixteen rooms, and is often fully booked well ahead of time by those "in the know". The building in which it's housed is truly beautiful and well worth a look, even if you are not staying at the hotel. The combination of a Castle Hill location and an incredible building is a winning one.
