My husband and I stayed at Vincenzo's apartment for 3 nights at the end of our 2-week trip to Italy. Vincenzo's place is perfectly located - literally steps away from the Trevi Fountain - and within walking distance to all the major attractions. It is also within walking distance of a metro station and the nearest taxi stand in Piazza Barberini is about a 5 minute walk. The apartment is right in the middle of the action, but on the 4th floor it is very quiet in the actual apartment and we did not hear any noise from the street. It has an elevator which is a bonus. There are 2 AC units in the living room and bedroom that kept the apartment cool and comfortable for us. The slanted ceilings were not an issue - you just need to watch your head in some areas of the apartment. The shower is also a tight squeeze so if you are a very tall/large person you may have some issues but my husband and I at 5'7" and 5'9" were fine. Keep in mind that this is an older Roman apartment building so it is no frills, but for the price and the location it is perfect for visiting Rome on a budget. Vincenzo is extremely nice and very easy to get in touch with too which is always a plus. There was an issue with the water in the apartment building on our first morning and Vincenzo responded right away (I called him at 7am) and the issue was fixed by that afternoon. He is a great host!
