Viewing recommendations

What's worth checking in person before deciding.

  • Test water pressure and temperature at the tap, in the bathroom and kitchen, for at least a minute.
  • Ask specifically where you'd park: is there paid city parking, who currently holds it, what the permit costs, and how long the waitlist is.
  • Look at the stairwell (cleanliness, smell) and the association's notice board: unpaid dues, conflicts, recent decisions.
  • Knock on a neighboring door and ask two things: what bothers them most often, and what work is planned for the building.
  • Ask for the latest maintenance bill from a winter month, not a summer one: that's where the real cost of living there shows up.
  • Schedule a viewing on a weekday too, between 6:00 and 7:30 PM, the window when the building is busiest: neighbors, parking, elevator.

Neighborhood recommendations are derived from public OpenStreetMap data and may be incomplete. Checking in person is still what matters most.
