The good and the bad. First the bad, the stairs to the 3rd floor are steep and very narrow and make it hard to carry a suitcase up so if you have mobility problems then it is not for you
The good - it’s in an excellent position, I could not think of a better neighborhood, it’s full of parisians and lined with good places to eat, bakeries, cheese makers etc. Its possible to walk to the major attractions but better to take the metro. It’s really brilliantly located. I would stay there again
