We stayed 4 nights in "the annex" of The Nags Head while attending the Goodwood Revival in Sept. Although the price was crazy expensive at £450 per night for a basic hotel room and breakfast, at the time we booked we couldn't find anything cheaper that was as close to the train and bus station. (It's an easy walk through the historic center, past inviting shops and restaurants.)
The "annex" rooms are around the corner from the main in and pub, and the separation was no problem. The area felt safe and it was quite quiet since it was not directly on St. Pancras Street. (Even St. Pancras is not a particularly noisy street.)
Our room was clean and comfortable, and breakfast got us off to a good start. (Have the smoked haddock if you can!)
But what made our stay most memorable were the attentive staff members who made us feel like were at home. Tom, Jimmy and Ricky (Rickie?) had smiles for us every time we saw them, and there helpfulness and cheerfulness were so welcoming. Nags Head is clean and tidy because Ricky takes her job seriously...and does it with a smile. And we felt like Jimmy wanted to be sure everything went well for us and that he'd help us solve any problem that came up. We really felt that we were surrounded by friends.
With such kind staff, we're happy to recommend The Nags Head!
