Excellent location if you want to attend Carnevale with no real expectation of sleeping until the wee hours of the morning. If you're going to sight-see, be advised that the apartment is on a main thoroughfare and the noise level is enough to wake a light sleeper. There are 5 steep flights of stairs to climb, and the beds are EXTRA firm.
On the plus side, it's close to the train and bus stations. It's a large apartment with 2 full baths.
