Super conveniently located bohemian little apartment: you'll be pretty much anywhere in the old city in few minutes.
Please note that there is no elevator and that the final steps are reeeeally steep: I would not recommend this accomodation to people who cannot climb stairs easily or have heavy luggage.
The apartment definitely needs some refurbishing (especially the electric sockets that look old and not very safe; also, you need to use the air conditioner instead of the heaters, which means that the bathroom is freezing, definitely not convenient in the winter): overall I don't think it is worth the price (which I could unfortunately say about most rental apartments in Italy), but the view is beautiful, there are plenty of good books to read if you know Italian and Carlotta is very nice and will provide tips and other useful information.
