Lorenzo´s flat is very small but perfectly sufficient for a few days stay. It has got all you need and uses the limited space in a great manner. It is renovated, modern and extremely clean so you will feel comfotable (just the mattress has had a few people sleep on it and is a bit tired :)). The kitchen equipment is only basic, however, you will most likely not want to spend your stay cooking five star meals so you won´t mind :)
Also the location is great, easily walkable everywhere via back streets so you can avoid most of the tourist craze.
Lorenzo is really nice and will help you with anything you need. We had a great time there and can reccommend the place to others.
