We have stayed at Marco's amazing place for 3 nights and had absoultly a wonderful Roman authentic experience. the flat is situated a minute from Piazza Navona, in a very quiet street. it looks exactly as it reflects from the pictures very clean and welcoming. the location was superb - a walking distance from all the major sites in ancient Rome. Marco's respond time was very quick. we didn't actually met him but the lady who came to welcome us was kind and spoke English fluently. the flat is at the top floor and there are a lot of steep stairs to climb to with no elevator. for us it was non issue but it is something to consider. the only downside was a poor supply of hot water with a wick water pressure. other then this everything was perfect for us. we highly recommend Marco's place and when we will come to Rome again would love to stay in his lovely flat.
