great stylish place with wonderful art and wonderful furniture pieces. I fell in love with the bar cart (which had no bottles but lovely to look at nonetheless). Location is perfect and despite being right the Trevi fountain (Piazza dei Crociferi.), there was no bothersome noise, the unit had good double pane, maybe argon gas in between windows. It felt like a sanctuary when you walked in and left the crowds behind. Be warned, 4th floor in Europe means 5th floor in the USA. It is a sobering trek up the stairs but once you are inside the apartment it was worth every step.
