If you're planning a vacation to Siena, I would definitely recommend Hotel Duomo. Whenever I'm on vacation, I always think the hotel's price for a given location is the number 1 factor. And on that scale, Hotel Duomo is great. A five minute walk from Il Camp and from the Piazza del Duomo, there's not much to dislike about the location. We took a bus to Siena from Florence, and the cab ride to the hotel was only about 10 Euro. And, in hindsight, would only have been about a 10 minute walk. Really the location could not have been better, and the rate we got I thought was low, so it seemed a very good value.
The hotel itself is pretty basic but is everything you'd need. The rooms were clean. Ours had a fantastic view out the back of the hotel to the Duomo. The hotel was quiet. They had in room free wifi, which was the best wifi signal of any hotel we stayed at in our 2 weeks in Italy.
The room itself was a little small, but it was fine for just myself and my wife, and we spent very little time actually in the room.
The breakfast was pretty basic but OK. There was no hot food, but they had a selection of meats, cheeses, rolls, cereals, and other cold items. They do not have a restaurant on site, but there are a number of places to eat within walking distance.
Everyone working at the hotel was very pleasant, although we did not make any difficult or unusual requests of them.
All in all it was a nice place to stay for a couple nights on vacation when your main focus is sightseeing, and I would definitely recommend it.
