Serena was absolutely wonderful. The room is perfect and comfortable and everything is as expected from the description. After check-in, Serena went off to do her own thing during my stay, so it really felt like I had the whole apartment to myself (that may or may not be the case with your stay). If you need a local SIM card, she has some available and can help you set it up with your phone if she has time--which was very nice of her and very helpful! Location is perfect--2 minute walk to Vauxhall station.
