This flat was the perfect spot for our visit to Paris. The flat is on the same block as the Metro Line 1 (which also connects to the RER B at Chatelet for those coming from/going to CDG airport) so you can get anywhere quite simply. It also within walking distance of many shops, cafes, brasseries and many of the cultural sights (Notre Dame, Saint Michel square etc).
I highly recommend this flat to anyone visiting Paris!
