My stay at Fabia's place was fab-ulous. The apartment was far larger than I'd expected: two big bedrooms (much bigger than I have at home), comfortable beds, a spacious living and dining room filled with comfy couches and antique furniture, walls lined with books and pictures. Kitchen's small but functional with a nice outlook over tiled roofs. Bathroom is good, although I could wish for a better shower - it's very small, good water pressure but with somewhat challenging temperature fluctuations.

The area is unbelievably wonderful. I'd been warned not to stay in Trastevere as it's considered party-central for Rome and way too noisy. I didn't find that at all. It's like a lively little village, which happens to be only a short walk over the lovely pedestrian bridge, Ponte Sisto, to a big, noisy traffic-congested city. It is a really charming neighbourhood, with a terrific selection of restaurants and shops practically at your doorstep. I had to resist the temptation to just spend my whole week in Trastevere, rather than venturing out to the very crowded major sights across the Tiber River.
The magnificent city of Rome itself is truly mind-blowing, but it was always an enormous relief to return to Trastevere at the end of a busy day. And there are a surprising number of historic sites, beautiful churches, museums and sumptuous villas to visit on your side of the river without crossing to the other shore. As well, I took an excellent half-day cooking class from a (real) Italian chef at "Cooking Classes in Rome", located just a five minute walk away (book well in advance). At night, just close your bedroom window that looks down into the picturesque cobblestone street below, and sleep like a log.
Early on, buy yourself a one week transit pass, at any tabaccheria (tobacco store), and locate the last stop for the trams and buses before they cross the Ponte Garibaldi, just a seven minute walk away on Viale di Trastevere. You'll find you use them a lot, particularly the trams, after you've had your first couple of walks into Rome over the Ponte Sisto.
Fabia is lovely person to deal with - very conscientious and (bonus!) she's fluent in English. She met me there and gave me a thorough orientation tour of the flat, and helpful tips about the neighbourhood.
