Nice property, with a lot of charm and historic character. Definitely spring for the garden view and note that although you might have a better view on the higher levels, we enjoyed our stay in Room 105 which was lovely and spacious-- it had an adjacent upstairs loft area with 2 single beds which would be great for a family with young kids. An added bonus was that it was only one level of stairs to get to street level. (The small elevator was a bit slow.) We were pleasantly surprised that the Palazzo also offered inexpensive wine for sale (from a barrel on the countertop) by the glass and carafe-- it was nice to be able to sip some wine in the garden and watch the beautiful sunset from the terrace. All the staff we encountered were friendly and courteous.
Free parking was a nice feature. Be sure that when you set your GPS, you take the route by the Porta San Marco gate. (Siena is closed to traffic in sections- not all city gates will get you to the Palazzo.) Breakfast was good (loved the croissants and their multi-grain, seeded bread-yum!) Would definitely stay there again.

We stayed in Siena for three days and booked at the Palazzo Ravizza on the basis of tripadvisor reviews and price. We were not disappointed. On checking in, we were given a room with a garden view over the hills west of the city. It was beautiful. The room was charming and the location was ideal for us. It was only a four-minute walk from the duomo but was pretty quiet. The staff greeted us warmly and gave us consistently good restaurant recommendations after carefully inquiring about what kind of dining experience we were looking for. In our case, we were aiming for a warm trattoria with a modern twist and they came through.

The hotel is very charming. The standard room was a little small and is not suited for longer stays. The views we had on the garden and the typical Tuscany landscape were very nice. You will hear the neighbors arriving at night, as the hotel is located in a historical building. The bed was a little too hard for a good night sleep, but this of course is very personal. The breakfast was ok.

We had stayed at the Palazzo Ravizza, an 18th c. building that had been used as a pensione since the 1920s, the last time were in Siena, in 2001. We booked there again, although we were disappointed that their excellent restaurant was no longer open. We had our choice of rooms, and took a more expensive one than originally booked because it had a desk and more space for bags. We took our bags to our room, then moved our rental car to the secure (and free) parking area at the back and climbed many steps to return to the hotel. Breakfast was excellent.
