My girlfriend and I stayed for one night in August. We arrived at around 5pm on a Saturday, was greeted at the bar, and taken to our room by the very friendly Gareth. The room is located towards the rear of the property through a separate (but attached) courtyard.
We stayed in room 1 (I believe of 4). The room was spacious, with a good sized double bed and the usual amenities. The bathroom was designed for those with disabilities, so if you are staying and have a disability room 1 may be a good one to request in advance.
The pub is located on its own down a very quiet country road. It is a fair walk elsewhere or into Hook Norton proper. We didn't mind this after a day at the Hook Norton Brewery, and was happy to spend the evening having dinner and drinks in the bar/restaurant areas. The food was very nice, good sized portions and made with extra care by a very good cook. We had starters and a main (no dessert as we were full). The homemade pie (steak & kidney this time) was very nice.
At least three Hook Norton ales are on tap, meaning this is a good place to stay if you fancy sampling a few during the evening. After our meal we did, and sat in with the locals. This is a dog friendly pub, and we really enjoyed making two furry friends during the evening.
Also to add that parking & WiFi is free, breakfast is provided in the morning (full English with orange and hot drinks) at around 9am, and check-out was relaxed too (11am but with some flexibility). A very relaxed stay.
