I booked a stay here after staring at it from my room at the Hotel Canal Grande across the canal as I was decided to extend my trip. I agree with other reviewers than the rooms are a bit dated. However, I still give it 5* because the view is really excellent, and I don't know why people would stay in a hotel by the Grand Canal if they're not getting a room with a view. I was there for the view, not the room. And I am very grateful they gave me a room with a balcony, I sat outside most evenings after the sun set, just soaking everything in and watching the vaporettos go by.
Also, this room was like half the price of the hotel I was staying at before, for a BETTER view. Hotels situated on this side of the Grand Canal have a better view over/into the bend of the canal imo (on the other side it kinda cuts off). The location is also very great if you're coming in from the Piazza, only one bridge to cross and then it's a straight path. So sure, the rooms are a bit dated, but people need to consider what you're paying... considering the price I find it's pretty impressive value and would definitely recommend.
Dinner at the Japanese restaurant was also pretty decent, I've had Japanese food a few times in Italy and it's the only one that is passable. That said I think I was charged for 2pax though I was solo, but it's not a big amount. I wish though that they had opened up seating outside, I guess they didn't because of the weather but in Covid situation I think many would like to sit outside even if it's a bit chilly, we can just throw an extra jacket on.
Staff were very friendly and helpful, and answered all my questions with warmth.
Also not sure why everyone is complaining about the size of the rooms, I'm not sure they are comparing it to other rooms in the area because most rooms in Venice are this size, it's quite a standard size so it seems an unfair complaint.
