I stopped by at Serena's for two nights and it is a great spot. The location is handy, right by Vauxhall tube, and there are a number of convenience stores nearby. The flat is spotless, neat, and the lounge and bedroom are light and spacious. Unfortunately I didn't get to meet Serena this time, but she was so incredibly helpful in her communication, and made sure I had an awesome stay. Excellent host and an excellent place to stop.
