"Jessica, I'm looking at AirBNBs in the Trastevere neighborhood in Rome. In the CT, did you stay in Monterosso? And do you have a suggestion for where to stay in Venice? I've been advised to stay "across the way" and "out of the fray" but I'm trying to figure out where that is:)."
We did stay in Monterosso. We rented an Airbnb there too. In Venice I have stayed in 3 places and my favorite was last year. The back story is that several of us like to lift weights, so I scope out gyms in the places we travel before I book, and then get places near-ish to the gym I like so I can go there in the morning. Lat summer is the first time I really did this and it turned out to make our trip so much fun. Speaking of going to places to just 'be'. We go to live there... and also see a lot of amazing things. So, the location we stayed in Venice last year was just south of the Chiesa di Santa dei Derelitti. The street was Barbaria de le Tole. What I liked so much was that we could walk everywhere within 20-30 minutes (from the Jewish ghetto all the way to the Basilica Santa Maria della Salute - which you must walk to, to see the view from the point of land it is on!) but the area itself was not swarming with tourists. It was near the gym, but also near a grocery store (the co-op) where we bought groceries for our breakfasts. In short, it felt like more of a hybrid between tourist area and resident's area. Also, it was close to the ferries, so if you take a boat from the airport to Venice, you will get off right near that area. We took a ferry to Murano one day and it was another easily accessible thing.
