Mario's place has everything you might need for a few days' stay - well-equiped kitchen, a balcony, a washing machine and a dryer if you need to wash your clothes. Mario himself is a very welcoming and responsive host. The only possible downside is the neighbourhood - it is relatively close to the city center, but it is a bit scary for me at night. The neighbours are also rather noisy, especially if you want to sleep with the window open. Apart from that, I definitely recommend his place. And it's out of the ZTL, which is great if you're there with your car.
