Former tenant·7 months ago

Overall nice building but VERY thing floors

Pros

Nice community, generally quiet

Cons

The floors are paper thin. I can hear everything my upstairs neighbors does, every step, their TV, even when they open a dresser drawer

Former tenant·7 months ago

Good building bad in house management

Pros

Units are great the tenants are awesome and the building common areas are usually very clean

Cons

the intercom system is almost nonexistent, building super absolutely does not answer the phone/ is not a huge help and is not very nice, and package management is so poor you can almost expect packages to get stolen, even though all are delivered inside the building in the lobby.

Advice to the owners

get better supers, replace the intercom system, incorporate a better package system
