Daniele and Patrizia had a very nice apartment in a great location. They had a coleague of theirs meet my friend and I at the apartment and she did a great job of showing us around. She did mention that they usually have couples stay with them and I think that this apartment is definitely more conducive to couples rather than not.

The shower is in the middle of the unit and out in the open. That may sound funny but it was very well done, it's just that at shower time we pretty much confined ourselves to our rooms to give each other some privacy which complicated our stay just a small bit.
Otherwise, the apartment was very clean and well decorated. The washer machine was a more than welcome amenity and a drying rack was provided, keep in mind there's no dryer.

Again, the location was also great. A short walk to the metro and an easy walk to the bars and restaurants if that's what you're looking for. One problem was that the upstairs neighbor's tv and footsteps were pretty audible at certain times during the day.

I would recommend Daniele and Parizia's place but it's still better for couples than a group of friends.
