We had a great time in Paris and the apartment was in a fabulous location. There are lots of places to eat and grab supplies within 200 metres! Highly recommend a roast chicken and potatoes from the butchers next door and the pastries from the Boulanger, also next door were sublime.
You can walk straight up the street to the Eiffel Tower in around 20 minutes looking at the Tower the whole way. Metro stations are 5 minutes walk away and the whole area was busy, vibrant and most importantly felt very safe.
The apartment has all you could expect. It's a little worn around the edges but we spent so much time sight seeing this didn't concern us.
