The flat is centrally located and Perugia is a wonderful place to visit. It is a good sized place, with two bedrooms, a kitchen and seating area, and a bathroom. The bedroom is comfortable with a large bed and wardrobe. The bathroom is well-appointed.
That being said, little thought appears to have been given to the comfort of the accommodations or updating it beyond the bedroom. The seating area in the kitchen offers a futon that is basically on the floor, which is hardly comfortable. The kitchen table is passable though the chairs were a bit wobbly even for small folks like us, and the dishwasher appeared not to have been used for awhile, so it has an odor.
The second bedroom has a piano and another futon, on wheels. As we did not use it as a bedroom, we tried to use it as a seating area to enjoy a glass of wine. You're in Italy and enjoying a pre-dinner glass of wine is all but mandatory! As the futon is on wheels, if you move while seated the whole futon slides, causing you to lurch forward without warning.
So your seating choices are the kitchen table, the floor futon, or the futon on wheels. No other chairs for sitting, which is odd.
Also, while the owner has no control over this, be aware that the area around the flat is quite noisy. Whether it was due to Halloween or college students being college students, the yelling in the surrounding area is loud and lasted each evening til about 2:00 AM or so.
