The apartment is located in a safe, pleasant and convenient area near the Les Gobelins métropolitan. In my personal opinion, I would say that the area is great: it is not overcrowded by tourists (mostly local inhabitants are living here) and everything what you need during your everyday life can be found here, ranging from fine restaurants and drinking bars to supermarkets and small local stores. Even a 15-minute night walk to the Panthéon is possible.
The rooms which we made use of were all clean. The host responded quick, and is open to help or give advice whenever this is needed.
Therefore, I would recommend staying in this cosy authentic Parisian apartment!
