Had a great stay at this flat. Conveniently located within minutes from the bus to Central London or the overground rail to Victoria Station. My sister and I were rarely at the flat during our stay but when we were, we had a very positive experience. We did not meet Mathias during our stay but Sally was very helpful and accommodating to our needs. She did a very good job of emailing me back in the days before our trip to make sure everything was squared away. The room was clean and of adequate size for two travelers. The living area looked very inviting as well but we were never there long enough to enjoy it. All and all a very good experience.
