Location! Location! Location! We were able to walk to most places (Vatican, the famous Piazzas, Fountains, etc..) There are many great restaurants nearby and a grocery store right down the street. Eva was very responsive to all my questions and was accomodating. The unit was big enough for our family of four. You need to walk up two flights of narrow, steep stairs which was not an issue for us (we only had carry-on suitcases), but if you travel with large suitcases or have issues with stairs, it may be difficult.
