Staying in Marios place was a good deal for me, as during Il Palio in Siena, most of the places were very expensive. His place is a bit out of the center, but its easily walkable to the center. Its much more calmer then the city and you can see the stars from the garden of Mario. The room was clean and I had a nice sleep in the bed. Internet was working really good. I just missed some body wash soap in the shower, but its very little issue. If you have a car, this place could be really good place where to leave it right next to Marios place. Especially during il Palio, there is really hard to park your car around the city. Dont know how it is in regular period. The car could give you a bit headache if you stay in the center. Its really nice to have a breakfast in his garden and also wine in the night. There is right next the house also bus going directly to train station. If you want to be right in the center of Siena, I would choose other place, but as during the 4 days i spent in Siena, I tried both( the center and outside the center, in Marios place), for those who like calm places its a right choise. Mario and I communicated by (SENSITIVE CONTENTS HIDDEN) translator, haha. But it was fun and Mario tried to help me in everything. He was a great host.
