Nico is an amazing host! Cristina was on vacation so we didn't get a chance to meet her, but I can't imagine a better host than Nico. He was very responsive and provided so many excellent recommendations. Take the restaurant recommendations for Zucca and Osteria Trefanti-- They were all amazing and delicious! Also, if you get the chance, Nico made us a dinner at the BnB and it was phenomenal. He's a great cook and it was a great romantic way for my husband and I to celebrate our Babymoon.

The BnB is wonderful and I can't recommend it more. Close the outter wooden window coverings to block any noise that might be coming from the Piazza across the river. I'm a light sleeper and I slept through the night. There are a few bars over there that can be quite lively until 11- 12pm. I've seen some negative comments about guests not feeling welcome in the space, but we felt very welcomed. The only room that's off limits is the kitchen. BTW, look at the furniture in the living room, it's beautiful family heirlooms that are older than the USA.
The bedroom is very cozy, well decorated and the bed is comfortable. I managed to come down with a cold while in Venice and Nico was a great host and provided extra blanket and pillows and checked in regularly to make sure I was okay and if I needed anything from the apothacary.
You get two breakfast choices, sweet or salty. Both are good.

Salty Breakfast: Salad with Ricotta, salamis and fruit. Bread. Fresh Coffee and juice.
Sweet Breakfast: Sugary pastries, cookies, breads with jams and honey, and fruit. Fresh Coffee and juice.

The only caveat I'd mention is if you go on the free Murano glass tour you have to pay for the Vappretto ($7 each) to come back to Venice. The prices were steep at the new murano glass factory (as in $1000 - $200000 for the art work.) It was a wonderful free tour and the glass work is amazing, but I felt like I should have had to pass a credit check before going. You don't have to purchase anything and Nico stresses this before you go, but the sales guys will follow you around and try to convince you to buy something for the "free" vapretto ride that you took to get there.
