We visited Siena in Oct 2011. We just basically walked off the street, asked if they had a room, looked at it - stayed for 2 nights. The room was quite small, but that didn't really matter for a few nights - not as if we needed to unpack everything! It was clean, ample number of towels, blankets etc. A bit dark as it had only one small window in the very high roof, but we didn't stay in the room very much. Ensuite bathroom was clean and well equipped. Shower was good. Location of this place was great - in the historic centre. Receptionists were friendly and knowledgeable. They helpfully printed out bus times to Florence and instructed us where to buy tickets etc. Breakfast was ok.

We stayed one night. The host was very kind and helpful. He recommended us to a restaurant that was the best meal we had in Italy. The rooms were average size probably quite large by europe's standards. The Wi Fi did not work in rooms which was a hassle for me since were were trying to line up wine tastings and get driving directions for the rest of our trip. The breakfast was pre packaged pastries, yogurt, and an auto coffee machine that made coffee from dried powdered coffee. YUCK!
Good directions and easy to find. Great location just minutes from anything in Sienna.

After reading the other reviews, I requested a quiet room, and it was practically silent. (We were travelling in mid-October) though I imagine it wouldn't have been if it was packed with students or something. But it wasn't. Everyone in the breakfast room was about middle-aged.

Decent value for the location. (although it's rather expensive to stay in Siena, compared with other, lovelier Tuscan destinations) And the charming night desk clerk bought my mother a cup of coffee when all she had was a 50 euro note.

If you want somewhere reasonably priced and perfectly located in the old part of Siena, then this is the place for you. It is near the bus station and shops, restaurants and a very good supermarket.

Plain white walls and simple rooms are quite a basic decor. The breakfast room is difficult to find and has no windows. Breakfasts are just about adequate. The staff are very friendly and helpful. Rooms seemed to be quite large and clean but there are no baths, only showers.
