Very well maintained apartment.
The entrance to the unit should be secure. Currently the door to the unit is open and accessible to everyone. Approach to the building was not very impressive, but the vicinity outside was busy and lively, very close to eateries, shopping and public transportation.
The apartment was spacious for us (family of 3 adults), cleaned well with air conditioning in every room.
The bathrooms are really small and one of them had a clogged sink and shower. Needs some fixes there. I would certainly recommend it to anyone touring Paris.
Overall a good stay!!!
