Palazzo Guadagni was reasonably priced, clean, comfortable and very well located. Our room was air-conditioned (very important, given how hot it was) and quiet (also very important). The staff was helpful and the hotel provided a nice breakfast. Hard to ask for more than that. I'd suggest requesting a quiet room if you're not a sound sleeper as the hotel is on a square and I gather it can be noisy if you're in certain parts of the building.
