While in London, my wife and I stayed at this Kennington property for 7 nights. The suite was adequate. Though we did not utilize it, the suite is equipped with a kitchen and utensils. It also has a washer and dryer. The location is less than a half block from the Kennington underground station allowing transport to almost any major London attraction in under 10 minutes. The area is fairly quiet, but you do hear sirens and the rumble of the underground; noise expected in any large city. We didn't find the noise bothersome.
A warning to fellow Canadian travelers (or any North Americans) a KING bed in the UK is actually a touch smaller than a NA Queen. We learned this the hard way. The washroom is also a standard UK bathroom with no shower curtain so be creative with water splashing. We thought with it being a basement suite it would have been cool, but the suite was HOT. After leaving the windows and patio door open in the evening, we managed to get the temperature to 22.5°C, but after closing things up at night, the temperature was back up to 25°C in morning. London was averaging 35°C though. As common to most London properties, the suite did not have central air.
As a whole, my wife and I continued to refer to the suite as "fine", or as I stated, adequate. It was not fancy by any means and lacked certain creature comforts we have come to expect when traveling. That said, it was a safe and clean place to lay our heads at the end of the day with a location for the price likely hard to beat.
