The Stage Door was a perfect little home-away-from-home for my week in London. The room exactly matches the photos and description, the bed is comfortable, and the provided towel is nice and fluffy. The bathroom is sparkling clean and modern, it's shared with one other Airbnb guest but I had it to myself for most of my stay, which was utterly luxurious for the price. Some other reviews mention a cold shower -- close the window and turn the temperature knob to about 2:00 and you won't have a problem. The toilet is separate and somewhat less deluxe, but it gets the job done while you get your job done. Amenities, on top of those mentioned, included multiple universal outlet adaptors, umbrellas, a thoughtful mini-fan dropped off at the door during an unexpected heat wave, and bottled water. The staff at the bar downstairs are also incredibly nice and helpful if you need anything in a pinch.
The location simply cannot be beat. It's easy enough to find, turn right on the left side of the very visible Old Vic theatre and walk straight for another minute. It's located a short <10min walk from the bustling Waterloo and small Southwark Tube stations. You can even walk directly to some attractions, I had a nice 20min stroll through the pretty neighborhood to Shakespeare's Globe to see Hamlet. Despite being located two floors above a pub, you can't hear the noise, and any outside revelers are quieted by closing the window.
All in all, I couldn't have asked for a better home in London. I honestly enjoyed coming back to the Stage Door a little more than some of the sights on my trip! If I'm ever in town again, I won't be staying anywhere else. Thank you so much to Kristina for the communication and the Stage Door staff for the hospitality.
