My experience in Claudia's flat was great. I stayed in her apartment with mu husband, baby girl (9 months) and my sister in law. We did not have the chance to meet Claudia in person, but she prepared all for our arrival and let me the keys with the cleaner. The location is excelent, just a few steps of Waterloo Station, London eye, Big Ben. You can take buses easily from every part of London and get to the apartment. The flat is big, clean and had everything we need to cook. Is a third floor without lift, but that wasn't a problem for us, even with the buggy. Absolutly recommended.
