This is a fantastic apartment. I quite enjoyed my stay. You can’t beat the location. It is an apartment in an older building, so if you have never been in an older building or are used to AirBnBs that are used as investment properties and not lived in, you should know that this apartment is a lived in and the building (and thus apartment) are older. Opening the windows at some point during the day is important for air circulation and to air the space out. I come to Paris annually in January and stay in Marais. This was the best specific location to date.
