This property is an architectural gem. If you appreciate clean architectural design, minimalism, and historic buildings, all rolled into one, you will love this place. Because of the position of the apartment, facing an interior courtyard and buffered from the street by another row of apartments, this place is extremely quiet, almost silent. I loved that! Near total silence in the middle of a busy noisy city.
The security is excellent with the doors and lobby staffed by a doorman something like 12 hours per day.
Be sure the check out the common spaces in the building. There are some lovely, well-preserved, 19th Century salons, now community rooms.
Minor down sides. Hot water is a bit intermittent and may require some patience. There is a working kitchen and cookware but bring your own salt, coffee, etc.
Very good communication.
