This map is from planning the route using the DB Bahn's website. From the border with Austria to Trento, the signs were all in Italian and German. That's because this area frequently went back and forth between the two countries.
Bolzano is the main city, but the mountains were the big attraction to us. I looked all over for a picture of what we saw from the train, but the link will just have to do. This is the only picture I got, and it looks very German/Austrian.
We arrived in Venice at about 6:00 in the evening. It was sunny and warm. We took a vaporetto all around the grand canal to our B&B. Of course it was dark and we were tired and hungry by the time we arrived. And it was Venice -- narrow poorly marked streets for people only, but we finally found the place. We called the owner and he came and checked us in, gave us our keys, etc. This was our room. We did have a private bath, but it was down the hall, so that was a bit of a pain, but we managed.
The reason there are so many links in this Venice part is that I only took those three pictures. We explored a bit the night we arrived. We planned to spend the whole day on Monday wandering around but it poured rain all day long. We took the vaporetto all the way out to Lido and back and were thankful we had good rain gear with us for walking around, but we ended up coming back to the room and going to bed early. 
Trout loved the park job of the car beyond the moped. He was to see many more of those -- especially in Italy.
The outdoor seating was right in the street. That's very common.
This is a different restaurant in another part of town. They're protecting their customers with a potted tree.
That evening we walked around our "neighborhood" and tucked in early. The next day was a day on our own in Rome, and it was time to do laundry. So we did that first, had lunch and then started checking things out. 
Trout was fascinated by some of the exhibits inside the church.
The church faces the Piazza della Repubblica. This is a great place to see cars swirling around the circle and a hard place to cross the street -- which we did too many times to count.
I seem to take the exterior pictures last and then forget to rearrange them when I'm loading them in. Anyway, here's Trout in front of the Basilica. It looks very different from the inside, eh?
This is as we go around the building. 
The baths museum adjacent is not the greatest, but we stumbled in anyway. It's filled with inscriptions and small pieces from excavations.
It has nice courtyards both out front and inside.
Look closely and you may see some a cat in this picture.
This is a very early Christian inscription. If I remember correctly, it is the earliest one found so far.
If you read the Rome with Ron posting already and clicked to the link about Mithras, you will probably recognize this image. It is very common in many works of art.
This was one of the most interesting parts of this museum for me. It was an exhibit of very early funeral urns, I think. But I'm not sure if they are recreated or original.
This is a part of the Baths of Diocletian, now being used as exhibit space.
This was a private bathing or dressing area. Images of various Roman Gods would be in the niches.
This is the ceiling of another private bathing or dressing room. 
This is back outside showing more of the area being excavated.
On Friday the 18th, we took the Metro to meet our tour guide for the Vatican. Along the way we stopped at some tourist attractions. This are the Spanish Steps -- without and with Trout.
From there we walked past the Piazza Mignanelli with its column of the Virgin Mary. 
We got out of the way of the fire truck.
And we reached the Trevi Fountain. It's supposed to be better at night, but we thought it was pretty good during the day.
We got back on the Metro and found our way to the meeting place for our Vatican tour. Fortunately we were early and were able to have some gelato before everyone arrived. Nutella is a big thing in Italy (as it is in our household). These were the largest containers of it we saw.
This was an "artisan" gelato shop so the flavors were all natural -- except maybe the Nutella. I got fig.

From the streets link above you can see that we were very close to Piazza San Marco and the Basilica, but we just didn't have the inclination to stand in the rain waiting to get in. Riding the vaporetto was fun in spite of the weather and we did manage to get lost on the streets, so we accomplished both of my goals. I just wish the weather had been better.
Tuesday the 15th we took the train to Rome. We arrived fairly early, got ourselves settled into our hotel and headed for lunch. It was a bit of a walk, but we ended up at this place for food at a time of day when many restaurants are closed. My Neopolitan pizza with anchovies was great and the tiramisu was the best I've ever eaten.

That evening we walked around our "neighborhood" and tucked in early. The next day was a day on our own in Rome, and it was time to do laundry. So we did that first, had lunch and then started checking things out. Our main stop was the Basilica of Santa Maria degli Angeli, built in the ruins of the Baths of Diocletian. The early work on the Basilica was done by Michelangelo.
