In our opinion, simply a great location and a perfect size for a Paris stay. We literally walked everywhere from the apartment but if you are not a 'walker' then the Metro stop is minutes away. There are enough shops, bistros and cafes in all directions to satisfy all of your needs or a great size fridge with cooking appliances if for one night or two you just want to rest up, have a glass of something and cook for yourself.
The apartment is super clean and is very quiet at night with a great pastry shop and wine café literally doors away and we frequented them often. Gemma and Lyron were terrific leading up to the booking.
Yes, there are two floors of stairs to climb but you know that beforehand (and they are beautiful stairs anyway, if that is such a thing). We would stay here again in a heartbeat if we were lucky enough to get back to Paris anytime soon.
