We have been to Paris on many occasions staying on the left bank this time we decided to stayed on the right bank.
Whilst the apartment was in a good location we were a little disappointed with the state of the bathroom and dust in the bedroom and most disappointed with the noise 3 out of 5 nights from the apartment above, after contacting our host he told us to deal with it ourselves as he was out of Paris. This was frustrating. If you are looking for a more refined stay choose the left bank for a few extra euro a night.
