My wife and I are travelling around UK and came across this on Late Rooms. 70£ breakfast inclusive.
More a Pub then a B&B. Room was spacious and facilities clean. Looks like recent regurb. We were tired so slept well but our room was directly over the beer garden so drinking and talking went on for awhile. Not raucous in any way though. I would however ask air a room away from beer garden.
Breakfast was lovely and amplly supplied.
Of special note is the attached restaurant which is excellent and seemed to attract many locals. A good sign.

We have just stayed at the Royal Oak to attend a nearby wedding. On arrival, the landlady made us feel very welcome and escourted us to our rooms personally. My only slight complaint (if you could call it that) was the way to the rooms which is out of a side door , down an alley and past the kitchens. This being said, once you reach the landing everything looks new- carpents, decor and furnishings. Our room was lovely and decorated with an elegant feel in black and grey with a very comfortable double, plus a single bed. The bathroom was large and looked new, with a lovely power shower.

In the evening we had a drink in the bar and commented on what a homely feel the place had. Breakfast the following morning was good and the Landlord was on site to prepare breakfast himself. I've no complaints to make at all about our stay. We hope to return there when visiting friends in the area in future as I think it's a little gem!

We wanted a weekend in the country and were delighted to find sheep in the field across from the pub. The setting is perfect, although the nearby bypass can be noisy at peak times. Duddington village is totally unspolit and filled with stone cottages. The Royal Oak is everything an English pub should be - friendly, popular with locals and welcoming to travellers. We were very impressed with Allen and Julia's hands-on approach, nothing was too much trouble. The food was good - the pub grub gives way to something altogether more special at weekends and the wine list affordable. Our room was pretty with brand new bathroom.
An excellent base from which to explore Stamford and Rutland and a great place to go back to.

Stayed one night in The Royal Oak hotel, its situated of a busy main road but back drops off the beautiful little village of duddington. Arrived to a frosty welcome from the bar staff and regulars and the night slowly got worse.. The rooms are clean below head height and access is through the back alley via the kitchen!!! not very practical with bags or kids, had to wait 2+ hours for a table even though many people came and went after us, staff were very vacant and seemed on a different planet, bar bill had gained 6 extra drinks and food was very, very slow to arrive once it did the stares started and comments to try and hurry us up... such a shame as it could be a lovely little experience if only in the right hands.
