Selfishly I don't want to recommend this jewel in case it gets so booked up that when I want it again it's not available. But in fairness to Lorenzo and Gea (the owner) I have to say it was the most beautiful apartment and best location I have stayed in in Rome - and I've been a few times now. And it felt like home for the two weeks I was there - including the pleasure of watering Gea's plants out on the balcony every couple of days because of the intense heat. In terms of location it is quite literally off of the Campo de Fiori (Rome's oldest fruit, veg and fish market by day and social gathering place by night) and very close to the Ponte Sisto which takes you into Trastevere. The apartment itself is spacious and pretty with lots of the owners artwork, photos, and personal touches which add to its charm and which gives the impression that it's a home away from home. It's also very clean and well organised. There are fans in the bedrooms and aircon in the living space. There is also wifi which works perfectly. The bathroom is a nice size with a bath and shower. The bells in the church on the Piazza Farnese below chime at 7am each day so you don't need an alarm clock. Lots of nearby restaurants (even on the same street!) and a nice little grocery store that has a fantastic ham and cheese counter and wine section.
The only negative if I can even call it that is that the building has no lift and the apartment is at the top of many stairs. When I arrived the owner Gea came down and helped me carry my suitcases up. But when I wasn't dragging my heavy bags the stairs became a welcome form of daily exercise.
I really would love to visit Rome again and if possible I would definitely stay in this apartment again.
Lorenzo as a host was excellent - he arranged a car to collect me at the airport, and was always quick to respond to any messages or questions I might have which weren't many as the apartment was pretty much perfect.
Many thanks
