The b+b is well located to reach the old part of Siena. We had a 'longer' car so sometimes struggled to find parking on the street- especially on market days. The room was spotless with a large bathroom and breakfast in the morning was perfect.
The only things I would take note of are:
1) the aircon is actually not in the rooms themselves but in the hallway. We had a fan which made some difference, but it was still very hot.
2) no elevator.. We had a lot of luggage- it was quite the workout
Otherwise, the b+b was super cute and exactly what we needed.
