Only some of the 15 rooms have private baths. You'll need to book well in advance because the price is inexpensive. The Riviera Hotel was quaint, the staff wonderful. And just one stop from St. Marks Square. Our room, in its self nothing to speak of, overlooked a canal and the hotel's beautiful gardens.
Breakfast is served on a lovely terrace.
If you want a sneak peak, rent Summertime, a Katherine Hepburn film shot partly in this hotel. We had two rooms, a triple and double. The triple was on the top floor, and was by far the nicer of the two rooms, although a bit nosier than the double. I believe the room number on the triple was 12. We weren't expecting the bathrooms to be set up the way we were, and were a little uncomfortable with them at first.
