We stayed at the Hotel Chiusarelli as part of a Rick Steves group tour. The hotel is located near the Basilica dell'Osservanza and approximately a 3-4 block walk from the Piazza del Campo. Our room was good size with two twin beds, nightstands a desk and a clothes wardrobe. We had 3 windows. At first the room seemed to be a bit warm and stuffy and we couldn't figure out how to control the air conditioner. I inquired at the front desk and was informed that the front desk controls the temperature of each room. They turned down the temperature and we were fine for the rest of our stay. The room was clean and the beds were comfortable. There were heavy, light-blocking drapes on the windows. Our room didn't face the main street, so the room was quiet. However, some in our group had rooms on the main street, which they said could be noisier.

Our room had a regular sized bath with a bathtub/shower combination. The water was hot with good water pressure. There is free wi-fi in the room, which requires a password from the front desk. Unfortunately, the password expires after a period of time and you have to keep getting new passwords, but the front desk was accommodating and friendly in this regard. Breakfast was good, with a wide assortment of items.

After a couple of days in Albergo Chiusarelli, my impressions were mixed. Nice and peaceful location, but only average breakfast. Clean room, but not especially clean bathroom. Much better look of my room than before (I've been in this hotel 2000/2001, and the interior was so grayish), but still pretty dark. Stuff very cordial (NB maybe not so warm if you cannot speak Italian language like me, which means: like an Italian), but service can be very slow, too.

Stayed here a couple of nights and I was not impressed at all. Booked the hotel due to its high rating on tripadvisor and was left dissapointed.
The service at the front desk was cold and not welcoming at all. The room, although spacious, was not 100% clean. The shower is very dirty with mold visible throughout. The toilet was also not in a good condition.
Breakfast also left a lot to be desired. The only positive is the location, very central, close to bus stops and all the big attractions. Hopefully the staff will correct these mistakes.

I had this hotel in mind to stay and my client also suggested since he is a local resident. Great hotel and fantastic location. The room was very nice and lots of space. The front desk was very nice and provide super service. The internet connection was even great. I could not find anything wrong. The hotel is so close to restaurants and places to visit. I love to walk and nice to reach everything. I wished that I could stay for Sunday since I love football and the stadium was right behind. I would go back tot he same hotel on my next trip to Siena and this was my first time.
