This pub used to be ok for a quick pint but it really has gone downhill so be warned. A lot of the other reviews are quite old (2008-09). We visited last week and the cramped shabby interior and unwelcoming atmosphere make this one to avoid. Have a search around; there are plenty of other much better pubs nearby.

With all of the excellent pubs throughout London, this is one of the few gems to visit many times over on your trip to London without feeling you're missing out some other potentially great pub.
Owner and manager, Binnie Walsh knows her cask ales and was willing (enthusiastic) to explain her excellent offerings, although she was a bit shy about having her picture taken.
Eight handpumps serve a delicious range of cask-conditioned ales. The Sambrook’s Wandle, Twickenham Original and The Dark Star Winter Meltdown were all perfectly conditioned! Sadly, it was early in the day and my wife had a schedule for us to keep. Just as well. A person can’t just sit drinking cask beer in a pub all day, can they? Anyway, the rest of the day seemed to float merrily along. Thanks for your concern!
Harp has a narrow, yet comfortable bar area downstairs with leather seating and a wide shelf to rest your ale and food upon. A mix of framed paintings from days gone by, line the walls on both floors. Stained glass windows and etched mirrors lend the illusion of a larger space.
Up the round staircase is a small, but well-spaced lounge area with an eclectic mix of comfortable antique chairs, sofas and tables. The walls are painted in muted shades of reds and pinks. Try to land the window seats if possible.
The Men’s room is oddly placed half-way up the stairs. Fortunately the door opens inward. Unfortunately, you may find yourself waving hello to passerby’s with your free hand. A friendly wink and nod will do if your free hand happens to be clutching your pint glass.
This pub deservedly gathers its share of CAMRA and Cask Marque awards and gets very high marks from many local London Guides.
The Harp is a true London treasure!

A really good, proper pub.

Excellent range of well kept real ale, friendly staff, great sausage sandwiches - an absolute diamond that should be held up as the blueprint for how to keep the best traditions of British pub keeping alive.

Booo!

The Manageress of this pub is awesome as far as we are concerned.
What a woman. She shows leadership, quality, stability and I for one would marry her. She needs to look out for me, as I am gunning for quality and beauty like that..............

Superb pub. Friendly, vibrant and with a range of excellent beers. SPBW London opub of the year 2008 -Well deserved.

A nice little pub (and little is the word!) with a good selection of ales and beers. Extremely central, it feels like a haven in such a central spot. Don't expect to get a seat, and the toilets are truly tiny, but a pleasant pub to have a beer, especially on a summers evening.

Proper pub,no tv etc,perfect real ale and plenty of it for a good price.Friendly too.
