Silvia's place is great, on Piazza Santo Spirito, which has great cafes and places to eat, is not too touristy but still close enough to the centre of town to walk easily. Silvia met us at the apartment herself to check in, and was flexible with check-in/out which was really useful. The apartment was lovely and has a great view over the hills out the back, and isn't noisy at all even though Piazza Santo Spirito is really busy at night (in a good way!). All in all would definitely recommend others to stay here, we had a great time (partly thanks to the suggestions Silvia left). Thanks very much!
