The location is good, on metro line 2&3. 5 min walk away from the nice cemetery, a must-visit, and easy access to the Austerlitz station, just pray for no strike.
To pass by the second door, you need to press the up and down buttons to find the owner’s family name, which took me some time, as this is probably different for people from Asia. The room is clean. The toilet is small.
The owner is nice. He is willing to help and provides useful info. Pity his dog is not on duty, so no comment on his pet.
