I stayed at Francesca's place for a week, partly for tourism and partly to attend a conference held at NYU's La Pietra campus north of the city. The location was perfect for this, with a 20 minute walk to the Duomo and 25 minute walk to the NYU campus. Francesca was perfect with communication, and she lives in the same building (on the floor below), and so is close at hand even though you have complete privacy within the upper floor apartment. The kitchen is well-equipped (with a Carrefour minimarket a short walk away), wifi is fast, and everything spotlessly clean. The only drawback I could point out is that the street outside (Viale Giovanni Milton) is quite busy so I would suggest bringing some earplugs if you are a light sleeper.
