So close to the castle in the centre of town. Changing of the guard directly in front of the hotel. Only a short walk to Eaton. Train nearby and parking is available.

Great boutique hotel, fabulous location in the heart of Windsor. Comfy beds, air con and lovely staff. Coffees at the onsite restaurant were the best we’ve had in the UM and just like at home.
