  • Poor management practices

    April 14, 2023
    The apartments are modern and well-designed, if a bit small and short on storage space, and the appliances are way nicer than what you'd find in a normal apartment building in Boston. However, there is absolutely no insulation between floors. You will hear every step your upstairs neighbor takes, and each one will sound like a 20-lb weight being dropped on the floor. It's a shame because the building is otherwise very peaceful, and the neighborhood is really a nice place to live. Update: ...
    After four months of living here, I have to take off a star due to issues with the building services and the finishings in the unit. Just too many problems for what this place charges in rent. As far as the building goes: 1) There's not a package room as is advertised on the website, and the package lockers have been down since late September, with no indication as to when they will be fixed. The building management blames the vendor, but they also haven't found any other solution to the problem. They just scatter everyone's packages all over the floor of the mail area, unsecured, and don't send any notifications when you receive something. 2) The after-hours maintenance staff isn't responsive. There's not a number to call if you have an after-hours maintenance issue; you just have to submit a request through the resident app and hope someone sees it. I had a lock-out issue once, and, after waiting a half-hour for a maintenance person to arrive and then another 40 minutes for the person to try to unlock my door, I finally just went and stayed in a hotel for the night. As far as the units, the main window in my apartment is without window treatment of any kind. Management said something about them either ordering or receiving the wrong kind of blinds for that window and then told me I could provide the window treatment on my own. Not OK for what this place charges. Update #2: I can now echo one of the other reviews here. I've had packages go missing as well. Contrary to what the website says, there is no "24-hour package room". Management just lets packages be scattered all over the floors by the mailboxes, unsecured and unorganized. Not even a basic level of competence on display here.

  • Poor noise isolation

    September 5, 2022
    The facilities are all very nice and new but the noise isolation isn't up to par. I can hear upstairs stomping, showering, running taps etc. Just moved in and it's already getting on my nerves
