This is a fabulous apartment for several reasons. It is as advertised - super quiet! This is great considering it is a 5 minute walk to a bridge towards downtown. Don't neglect to visit the local area - we went to one fantastic restaurant nearby, trattoria Angiolinos, via di Santo Spiriti. We ate a few other places but while the prices were similar, nothing compared to Angiolinos. Professional staff stood out - a charming waiter flirted with us all night - and the food was fabulous.
Maurizio has put together a very nice apartment with decent cooking equipment, and its a very large space - we were happy to hang out in the apartment which I cannot say for all airbnb places. The window views are lovely out the bedroom, and the space itself is beautiful. No elevator though!
Highly recommended unless you are over 6 feet - the doors to the kitchen and bathroom are very low. I am 5 foot 11 and hit my head several times on the stone doorways!
