We had a great stay at Karen's place. Her apartment is small but very nicely decorated and homey. It is extremely close to the Elephant and Castle train station, which makes it really easy to get everywhere around London. Karen was so nice and helped with any issues or questions (problem with hot water, getting a hairdryer, etc). We checked in early and she made arrangements to leave the key for us, which worked out great. Karen's place was adorable and great for a quick visit to London!
