The apartment is at a convenient central location - very close to Line 3 Temple and Arts et Metiers Metro stops; a bit further to the Republique hub. Be aware that there are no elevators in most metro stops, necessitating carrying luggage up and down a lot of stairs!
The ground-floor apartment was clean, quiet, secure, and well appointed with very fast internet. After spending time in hotels, it was great to have more space, a kitchen, and a clothes washer. There is no clothes dryer (just a drying rack), so keep that in mind and pack quick-dry fabrics (not cotton). The air conditioner worked very well!
Fabrice was super responsive and helpful in providing the location of the MonoPrix store near Temple Metro for groceries and incidentals. His suggestion of downloading the official Bonjour RATP app for the Metro was appreciated. We went through the convoluted process of buying a one-week Navigo pass for our phones/Apple watches and the technology did not always work as it should. If we were to do it again, we'd buy paper tickets at a station for the same Navigo passes. The flan at Le Petit Parisien was fantastic (just around the corner on Rue du Vertbois).
We would definitely stay at the apartment again!
