This is a good location for anybody needing to stay for business in the area as many of the banks and other businesses are in this area. It's also great for 2 friends or 2 couples. It's well located next to several underground stations which makes the rest of the city very accessible (Bank, St paul's, mansion house). Walking to the Tower of London, Tower Bridge, St. Paul's Cathedral and even the Tate Modern is pretty easy from this location. Just around the corner is a pub where Sir Christopher Wren had an office so the whole block feels very historical and charming, but also very active during the work week. There's a lot of stores within a block or two for groceries. While it feels surprisingly secluded, it can be a bit noisy with some nearby pubs, and noise in the alley mostly from people moving garbage and bottles and cleaning up, but not excessively noisy compared to most city apartments.
Pay attention to your checking in instructions, it can be a bit tricky to find the place and the key, but overall I had a good time staying here and would recommend it.
