The apartment is well organized and decorated for the small space that it occupies. The living room/ dining area is cozy, and the bed is very comfortable (it is very firm which I appreciate, my wife prefers a softer mattress).
Communication with Federico was very easy, as his responses were prompt.
We found the recommendations in his book to be very accurate regarding quality bakeries and local attractions, so feel free to do less planning for this portion of your trip and trust his recommendations.
***The washroom has a very small doorway, and the stairs to reach the loft bedroom are equally as small. This was not a problem for us, but if you are on the larger side, I would recommend you look elsewhere, as this detail could dramatically change your comfort level.
