We had a wonderful stay due to the following:
1) very responsive host- whenever we contacted the host, he responded immediately, he also prepared some fruits and drinks before our arrival as well as maps and suggestions for useful apps for Paris
3) location- the subway stop bonne nouvelle is just few steps away and another station few minutes. But we didn't need to use it as you can walk everywhere. We walked to louvre, grand palace, marais...
4) easy access to restaurants- we loved the montorgueil area filled with restaurants and shops (5 min walk)
5) our family of 5 had a comfortable stay!
