I had a truly lovely experience with Ari & Luce.
Their house is old and very Venetian-looking, but everything has just been renovated, so it's all pretty and modern. The location could not be better: it is only a few minutes walking from the Rialto and Piazza San Marco, yet just a tiny bit away, so you get a better feeling for what it might be like to actually live in Venice.
The room is excellent: spacious, with really high ceiling and two big windows. The bed is comfortable, and I slept really well. The ensuite bathroom is great, all brand new, with modern fixtures.
Everything was spotlessly clean. And the room smelled nice... a smell that put a smile on my face every time I walked in.
That alone would have been enough for a great experience. But what made it feel truly lovely was Arianna and Luca. They are amazing hosts, and made me feel right at home. They went well beyond what would be expected to make me welcome and to help me with everything they could. I can honestly say my experience in Venice would not have been half as nice had I been staying in a different place. I wouldn't think of staying anywhere else if I were returning to Venice, and I warmly recommend it to anyone looking for a really nice place with really nice people.
