Great modern, clean apartment off the street and equidistant between Bastille and Ledru-Rollin Metros.
Plenty of good shops, restaurants, and grocery stores within quick walking distance.
We stayed here with our kids aged 10, 7, and 5 for 3 days in August and it met our needs perfectly. Great A/C and TVs setup with Netflix/Amazon for a couple of hours of downtime in the heat of the afternoon :)
As others have mentioned, two bedrooms (only) are below ground with a narrow spiral staircase leading down, and you will feel the vibration of the Metro down there during its hours of service. This might be an issue for some but it wasn't for us.
Only nitpick is that trash bags and dishwashing liquid are not provided at this rental. Bit of a silly/unnecessary inconvenience, but no biggy.
