The apartment is in a great location in Chinatown with a fabulous wine bar directly opposite. Although the apartment is on a busy street being at the back of the building it is very quiet and we weren't disturbed at all by any noise form the street. There are plenty of restaurants close by but if you prefer to eat in there is everything you need to cook a meal.
We walked everywhere - about 20 minutes to the castle - but if you prefer to use the metro it's really easy to navigate and inexpensive.
