We had a very enjoyable stay in the Grand Hotel Continental. We chose the Noble Suite and had a room almost identical to

The room was very pretty, with high ceilings, lovely frescoes and a good amount of space. Larger room seemed to be duplexes, which we don't like.
The staff were uniformly helpful and eager to please. Breakfast was quite tasty with a nice assortment and some very high quality food. The location was perfect.
Highly recommended if you're visiting Siena for the usual attractions.
