Paola’s apartment is in the San Marco area, so everything is within walking distance. I even walked there from the train! It was about 30 min and a little hot, but I only had a backpack and didn’t have to worry about pulling luggage up and over the bridges and stairs. Plus, I had the opportunity to see some wonderful sights along the way. It definitely is suitable for only one person, but is also definitely good for solo travel. Ask Paolo for his restaurant recommendation, as I went there and everything was delicious!
