The breakfast was not very good at all probably due to restaurant renovations." - "Great stay!!!" - "Customer service was great! We had our next door neighbors making so much noise around 2 am which woke me up . Breakfast was not so good, good thing I asked just for one time.

- "Much improvement since change of ownership to Hilton, we travel through Winchester a couple times a year and have always stayed at this hotel which was under another name. Not sure if all renovations have been completed but it would have been a plus to have a chair (small office chair) instead of a small leather stool which was the only seating available at the work desk. Secondly the refrigerator was seating on the floor (small fridge) had to kneel down to access, there was a shelf rigt there in the same area the would have been a perfect spot to place the fridge. Minor adjustments which I hope the will get domne. Overall a great + expreience at the Spark !"
