Catherine was the perfect host. The place is easy to find and she leaves you to just get on with things - exactly what we wanted during our relatively short break. There's instructions that explain all the basics but I'm sure if we did need to email or call, she'd get straight back to us, she was quick with all other emails leading up to our stay. The apartment is so nice, there's loads of social space, good for breakfasts if there are a few of you and also a short walk from the train to get into the city.
Thanks again!
