I had a lovely say at Rita's. Her husband picked me up at airport and he also does currency exchange.
Rita's apartment's cosy, I was welcomed with some prosecco. The apartment is on the second floor so you'll have to climb some stairs. It's in a neighborhood within walking distance of some attractions. If you have heavy, luggage it might be an issue as there is no elevator.
It is very noisy in the neighborhood, up to 4-5am. I am a light sleeper. I guess it's an authentic Italian experience ahahaha, the neighborhood if you get what I mean. It could also be because across the bridge is a lot of nightlife.
Be careful on the stairs, I almost fell down twice during my stay. One day, the hallway light was out and it would have been a bad day if I didn't catch myself. The second was when carrying my luggage during check out. This is all outside her apartment but it's a note to be careful on the stairs.
Also note since the streets are cobbled, dragging luggage is increased work :) You'll get your work out for sure!
The bathroom is very small so if you're tall, it might be an issue going in and out. It also doesn't drain well, so there might be a flood. Be sure to put towels on the floor.
Rita provides some food/snack/beverage items in her unit and basic amenities you might need. There is also tv with Netflix and co if you have time to watch tv. The apartment was very clean and beautiful.
If you're not sure what to do, there are books about touring Italy on one of he bed stands.
As for transportation, I pretty much walked almost everywhere. You cannot use the metro as it's pointless. The taxi stand is a bit of a walk (the one I went to Piazza Venezia closest to me, there was one supposedly closer but I never saw a taxi there) there is also one in travestere, about 8-10mins walk.
There is a lot of food options to choose from in the neighborhood, or if you venture out, food galore. I definitely recommend staying at Rita's. The hosts were so nice and helpful with questions as well.
