Returning to Ca' Pisani I found the hotel to be every bit as lovely as I remembered. The service is excellent – all the staff we encountered were friendly and efficient – and everything seems to work very smoothly. The decor is great; the mix of contemporary and deco works really well and provides an welcome antidote to the excess of traditional Venetian interiors.
The breakfast buffet is excellent – I particularly like the DIY orange juice and the delicious cake – be prepared from envious stares from passersby if you eat outside (worth it for the opportunity to watch the city wake up and start the day) and the café/bar is also an excellent location for an early evening Aperol spritz (something my friend and I discovered a couple of years ago while staying at a different hotel).
The easiest route to the hotel from Marco Polo is the Alilaguna waterbus to Zattere (about 80 minutes on the blue line; not speedy but arriving in Venice by boat is great). From there it's a very short walk with no bridges to cross. Laguna, just by the waterbus stop, is good should you need an aperitivo while waiting for the waterbus back to the airport.
The hotel has a roof terrace which is small but nice with interesting views (if you're up there at night and see a string of lights in the distance, the answer to the 'what's that bridge?' question that may pop into your head is 'd'oh, it's a cruise ship!') and a few sun loungers (plus shower). There's a sauna which I've yet to use (and consequently can't rate on here) and there's no swimming pool (this is Venice; if you want a pool head for hotels on the Lido or the Hilton on Guidecca) so I've no idea why that's showing up asking to be rated.
A stay at Ca' Pisani is certainly not the cheapest way to see Venice, but in my view it's well worth the expense. If I possibly can, I certainly plan to stay here again on my next visit.
