We are going to be in Rome and Venice in July. I would love to get recommendations for places to stay in both Rome and Venice. In Rome, I've considered the Trastevere area but would also consider areas near the Collisieum or other historical sites for convenience. Rome will be our last day and we will be taking the train to the airport in the am of our last day so I'd like to have that in mind as well. Places to eat, local type "hole in the wall" places are what we love to find. Any other Rome tips are appreciated.
As far as Vienna, we don't love crowds and have looked at the Dorsoduro area to try to get a little more laid back and quiet area to serve as our base to explore. We will be flying into Venice to start our trip and from the best I can tell, you can take a water taxi from the airport directly into these areas but I could be wrong. Again, any other tips for our stay in Venice would be great.
Finally, we will maybe stay a couple of nights in Siena and would like some recommendations for restaurants or other things we need to see in that area. Even some of the ins and outs if we decide to rent a car there to go see the countryside.
Thanks for your input!
Any hidden gems for lodging, restaurants or places to see would be welcomed.
