Room was adequate and clean. But beds were not comfortable, Door knob was loose. As soon as I opened a door to the room, I smelled stale cigarette smell. There seems no air condition so need to open windows to get air through room. Room was ready to check in 30 minutes before check in time and no problem to get in to our allocated room upstairs. Expedia listed contact number was wrong and finally found correct phone and contact email address from Charles House own web site. Expedia booking site was not able to amend number of guest from one to two. I finally got Charles house owner by email and at end we paid additional 10 GBP for our stay. Toilet sheet was yellow stained and could not understand why it has not been replaced to new one. Better maintenance of room is required. 10 minutes Walking distance to Windsor Castle. Closest parking was full but we found spaces in another parking. Parking 4.80 GBP for two hours, 2 GBP for Overnight 7 pm to 9 am. Better to stay outside of Windsor or visit from London by tour or rail.
