We stayed at Marco's flat for three nights and it was wonderful. You get to stay in a real neighbourhood and get to have good food at Marco's recommendations. I would suggest you come in during the middle of the day and you can get a good feel for the neighbourhood. The flat itself is great and fits us fine. We have four children (2 teens) and the bigger room was great for them.
Marco helped us for about an hour or so, answering our questions and helped us with internet service and everything.
If (when) we come back I would definitely rent from Marco again.
